2. Description of the Related Art.
The use of Computer Aided Design (CAD) application programs is well known in the art. CAD application programs are often expensive, complex, and difficult to learn how to use. Additionally, architects, contractors, engineers, owners, and other parties involved with a project (referred to as project participants) are often mobile or at different locations. With new technology and the increased use of the Internet, project participants often have computers, Internet access, and personal digital assistants (1'DAs). Further, the coordination and exchange of information between project participants can be increasingly complex. Existing prior art applications allow a user to download a drawing, edit the drawing, and upload the drawing after completing the edits. Further, the prior art does not provide the ability to capture a visual/virtual desktop from a computer to a hand held computing device or vice versa. These problems may be better understood by describing prior art handheld computing devices.
Prior art handheld computing devices (also referred to as palm PCs ox personal digital assistants (PDAs)), axe often used to access and utilize personal information. Many handheld computing devices are available in today's marketplace.
Typically, handheld computing devices are only slightly larger than the size of one's palin (hence, the name palin PC) and have a small display screen for viewing a plethora of items. Software can be installed on a PDA to provide enhanced functionality. For example, a personal productivity tool may be installed to provide access to a calendar, contacts, email, Internet browsing, audio books, and audio recording capabilities. Card slots may also be available to provide additional memory or other functions (e.g., a modem). Additionally, some PDAs have infrared (IR) ports for communication. As described above, PDAs (including available software) do not provide the ability to view and manipulate a virtual desktop. Further, the prior art does not provide for a virtual PDA that may be viewed and manipulated on a desktop computer.

Studiodesk'~M provides the ability to store and access plans, drawings, sketches, etc. Access permissions can be defined to provide access for those persons working on a project such as architects, contractors, interior designers, structural engineers, etc. Additionally, information in Studiodesk~'~M
(such as drawings, plans, etc.) may be edited and modified in real time using a Studiodesk'~'~' application (by a person with proper access permissions) using simple easy to use tools. Further, StudiodeskTM provides the ability to interact with other applications on the desktop including transferring information to StudiodeskT"~ (or a web site provided by StudiodeskTT'~ from the desktop (and vice versa), and using related programs in both StudiodeskT"' and the desktop at the same time.
Notebook-like applications may also be provided and available to a user.
Such applications provide a similar interface on both a personal digital assistant (PDA) and a personal computer (1'C). Information may be dragged and dropped into the notebook on the PC and will automatically be available on the PDA
version (after synchronization) and vice versa. On the PC, the notebook floats in a window above all other applications and can be used as a graphical clipboard to txansfer/associate data between applications. Further, a notebook on the PC
may be a full-fledged virtual PDA. In addition to providing the functionality and graphical user interface of a virtual PDA, support for additional PDA-like applications such as spreadsheets, to-do-lists, calendars, etc. may also be provided. Thus, a virtual PDA
that can be moved and synchronized with a web site, local computer, and actual PDA may be utilized.
One or more copies of a software tool (e.g. a pen) may be obtained.
Thereafter, each instance may be assigned different properties (e.g. color, line thickness). A custom set of tools tailored to a particular task may be created. For example, a user can create a set of three colored pencils, instead of having only one pencil and continually changing its color back and forth, as in current applications.
New tools may be added to an application by dragging and dropping one ox more tools from a website onto the application. Such tools might be charged for on a per-tool basis, or by subscription, or by leasing, or by offering a free trial period with an option to buy. Further, such tools may be created in the form of an applet.
Thus, items can be represented digitally and manipulated by the applet tools in real time. For example, an applet tool may be created to select a particular point on a wall and dragging the point such that the entire wall is raised or lowered.
Another tool may consist of a knife (or cutting tool) that may be used to cut away sections/portions of a model or objects of a model such as a wall or ceiling.
The background of the application window may be transparent such that other applications may be viewed behind the window on the PC display. In essence, a transparent window enables the use of virtual tracing paper that provides the ability to overlay several independent documents while maintaining transparent capabilities/properties of each document. Data visible behind a transparent window may be captured and incorporated into an application, where the data can be annotated and otherwise manipulated as a bitmap image. Thus, the transparent window may be used to trace over an item in the background. In accordance therewith, a plan may be displayed in the background, a transparent window may be placed over the plan, and an architect may trace modifications to the plan or variations of the plan for discussing with other persons such as the client or contractor. Further, the transparent window may be a window of an Internet browser. In accordance therewith, the Internet browser may be modified or the properties of the window may be configured to permit the transparency and tracing capabilities.
Information may be stored locally when a user is not connected to the Internet. However, once the user connects (or logs into the web site), the information may be stored remotely on the web server. By storing information in this manner, synchronization between multiple parties accessing the web site is accomplished more easily. Further, while connected to the Internet, multiple users at different locations may have the ability to access and edit workspaces and documents simultaneously, while seeing each other's edits as they are made.
Specific Embodiments A web-based architectural design environment referred to as STUDIODESKTM or virtual desktop may be provided. On the virtual desktop, a designer can create, edit, view and manipulate design documents, including sketches, hard-line drawings, models, images, schedules and specifications. FIG. 4 illustrates the creation/editing of a sketch 400 in a virtual desktop. Documents and data are stored on a web-server, so that project data can be accessed anywhere. The environment and user interface may be optimized for pen input, although a mouse, trackball, or other input device may also be used. FIG. 5 illustrates a virtual desktop in accordance with embodiments of the invention. As illustrated in FIG. 5, other applications such as the Explorer application 500 may interact with and run simultaneously with the virtual desktop. For example, a file identified in the Explorer application (e.g., a picture 502, plan 504, or notes 506) may be dragged and dropped onto the virtual desktop.
Instead of attempting to automate the architectural process, a virtual desktop provides a set of fundamental and powerful tools that, in the hands of a skilled user, can be used to realize and document architectural designs. The user acquires and arranges their own custom set of tools to suit their tasks and work habits in the virtual desktop. Data objects and structures are kept simple and close to the surface, giving the user maximum control and flexibility. It is left to the user to impose meaning on the data, at the appropriate level of abstraction.
Structure of a Proj ect FIG. 6 illustrates the structure of a system in accordance with one or more embodiments of the invention. The STUDIODESKTM software 600 consists of various sites 602 made up of projects 604. A project 604 consists of documents held on a server. These include all the sketches, drawings, models, program notes, specifications, schedules, video, audio, photographs and other digital information used to design, specify and manage the project. Users access the project documents through the virtual desktop running in a web browser. The documents are organized into a hierarchy of sites 602, projects 604, workspaces 606, archives 608, and documents 610.
Sites 602 A site 602 is a collection of projects 604. A site 602 corresponds to the organization managing the various projects 604. For example, an architecture firm "A" may have a site 602 called "A" on a web server. Site "A" contains projects managed by "A".
In addition to containing projects 604, a site 602 can have a collection of workspaces 606 and an archive 608. In this sense, a site 602 is really no different than a project 604. A site 602 is given a special name just to clarify its role in representing the real-world organization managing a collection of projects 604.
Projects G04 Under a particular site G02, workspaces GOG and documents G10 are organized into projects G04. Each project G04 may have its own URL. A project is like a folder. A project G04 can contain workspaces GOG, document archives G08, and other projects G12 . For example, a firm like "A" might have a single project G04 called "A". This project G04 might contain sub-projects G12 for individual buildings.
If it makes sense, each building project G12 could be divided into sub-projects G12.
Projects G04 (and sitesG02) control access to their content. Each project G04 may have an access control list (ACL) that lists the users who axe allowed to access the project G04 contents and the level of permissions for each user.
Permissions may be inherited but can be overridden by sub-projects G12 or individual documents at any level. The default is to provide open access. Restricting access may require a deliberate action by an owner.
Workspaces 60G
A workspace GOG is a container document that may be directly edited. A
workspace GOG contains links to project documents G10, displayed graphically on the workspace GOG surface, including 2D drawings, 3D models, images, notebooks, word documents, spreadsheets, etc. FIG. 7 illustrates multiple documents/files on a project G04 workspace GOG in accordance with one or more embodiments of the invention. The key function of the workspace GOG is to allow a user to organize documents G10 visually. A user can place documents G10 side by side for reference, or superimpose them like tracing paper.
A user can create any number of workspaces GOG. Each workspace GOG may have its own URL. The state of each workspace GOG is persistent such that when the user returns to a particular workspace GOG, the documents G10 the user was working on in the workspace GOG will be opened in the position that the user left them.
Documents 610 Referring to FIG. 7, the actual data that a user creates, edits and views is contained in documents. A user can access one or more documents by placing the desired document on a workspace 606. Examples of such documents include 2D
drawings 700, 702, and 704, 3D models 704, images, notebooks, word processing documents, spreadsheets, videos, audio recordings, digital photographs, or any other type of multimedia document. As illustrated in FIG. 7, numerous view of the same model/drawing may be displayed simultaneously. For example, view 706 illustrates a side elevation view of model 704. View 700 also illustrates a top view of the same model. Further, FIG. 7 illustrates the creation/modification of a document in a workspace. For example, a user may identify a point on a wall or ceiling of model 704, and drag the point up to raise/lower the ceiling. Various shapes and tools may be used to work with documents as described below.
The same documents can be opened in more than one workspace 606 at the same time. If both users have edit permission, both may edit the document at the same time.
Accordingly, referring back to FIG. 6, documents 610 contain the actual project 604 data, including designs, construction drawings, specifications, etc. The goal is to provide access to the data contained in the document 610 as immediate and direct as possible. Borders and widgets framing a document 610 may be minimized.
Further, tool actions apply to whichever document G10 is under the tool.
Every document 610 in the workspace 606 may have a title bar at the bottom that shows the document 610 name and contains icons for document 610 related commands. A user may drag a document 610 by the document's 610 title bar to reposition the document 610 in the workspace 606. A document 610 may also be resized by dragging a corner or edge. Such a resizing may enlarge a document's size without scaling an image in the document. Dragging by a graphically differentiated corner of the document 610 may resize the document 610 and scale or zoom its contents at the same time.
Document 610 related commands are accessed through icons on the title bar or a pop-up menu accessible through the document's 610 tide bar. Such commands may include "Close document", "Minimize", "Print", "Export", "Send", "Cut", "Copy", and "Paste". A document 610 title bar may also contain special commands that only appear for a certain type of document 610, e.g. "Forward" and "Back"
for a web document 610 or "Layers" for a layer stack.
Documents 610 may interact with and be layered on top of each other. In one or more embodiments, Studiodesk'"~f defines interfaces for each document that allows the document 610 to retrieve information from another document 610.
Such retrieved information may include a scale that allows documents 610 to scale appropriately to each other, an origin that allows documents 610 to be positioned so that their contents align correctly, and geometric snap information that allows geometry being drawn in a document 610 to snap to geometry in another document 610 under the first document 610.
The draw order of documents 610 on a workspace 606 may be changed using a "Draw Order" tool. Other document properties that may be viewed and/or edited may include Tide, Author, Creation Date, Color, Transparency, Scale, Grid Resolution, etc. Such properties may be edited using a property sheet accessible from a document 610 pop-up menu (or possibly from an icon on the title bar).
Various document 610 types may provide different functions and capabilities to a user. In accordance with one or more embodiments of the invention, the following document 610 types may be utilized:
(1) 2D paper - A document 610 used for creating and modifying. two dimensional (2D) drawings (e.g., a sketch, hardline, etc.). Properties for 2D
paper may include a variable transparency, scaling capabilities, zoom capabilities, resizing capabilities (e.g., by dragging a vertical or horizontal edge to add more paper), resealing capabilities (e.g., by dragging a corner to re-scale/resize the drawing), and importation capabilities (e.g., DWG files may be imported into the virtual desktop 900 drawing format).
(2) 3D modeling sheet - A document 610 type used for creating and modifying three dimensional (3D) models. Multiple 2D and 3D views may be shown/viewed at the same time.
(3) Notebook 912- A document 610 type that provides a container for workspaces 606 that allows a user to flip through the workspaces 606 similar to pages of a notebook. Since each page of the notebook 912 may comprise a workspace 606, the notebook 912 may contain any combination ox arrangement of documents 610.
(4) Layer stack - A document 610 type that provides a container for workspaces 606. A layer stack is similar to a notebook 912, but the pages may be transparent. A layer stack may be used to create the equivalent of a layered drawing.
Since each layer is a workspace 606, the layer stack may contain any combination or arrangement of documents. A layer stack may also be referred to as a container or composite document 610. As described, such a composite document 610 may provide for graphically associating multiple documents of various document/media types. Further, such a composite document 610 may be moved between two or more workspaces 606 as a unit using a graphical user interface.
(5) Other workspace 606 - A document 610 type that provides a graphical link from one workspace 606 to another workspace 606.
One or more mechanisms/areas may be utilized on a web site. A variety of different types or differently structured/organized web sites may be provided.
FIG. 3 illustrates the desktop in accordance with one ox more embodiments of the invention. The desktop provides the user with an area to work 300 with pen-based input for sketching, drawing, and 3D modeling. The desktop is comprised of a virtual work space area 300 and a toolbar 302. Toolbar 302 may contain one or more basic drawing tools for working in drawing space 300. For example, a pencil 304, pen 306, or tracing paper 308 may be supplied in toolbar 302 to utilize and create sketches, drawings, and 3D models in virtual drawing space 300. In virtual drawing space 300, the user may move pictures 310, models 312 or may create and modify drawings 314. Further, each of the objects in drawing space 300 may be moved around or hidden by the user (similar to a physical desk).
As described above, embodiments of the invention (hereafter referred to as a "web site" or "StudiodeskT"'") may make an architectural web site/application/database available to users. Studiodesk'~M provides the ability to store and access plans, drawings, sketches, etc. Access permissions can be defined to provide access for those persons working on a project such as architects, contractors, interior designers, structural engineers, etc. Additionally, information in Studiodesk~'~M
(such as drawings, plans, etc.) may be edited and modified in real time using a Studiodesk'~'~' application (by a person with proper access permissions) using simple easy to use tools. Further, StudiodeskTM provides the ability to interact with other applications on the desktop including transferring information to StudiodeskT"~ (or a web site provided by StudiodeskTT'~ from the desktop (and vice versa), and using related programs in both StudiodeskT"' and the desktop at the same time.
Notebook-like applications may also be provided and available to a user.
Such applications provide a similar interface on both a personal digital assistant (PDA) and a personal computer (1'C). Information may be dragged and dropped into the notebook on the PC and will automatically be available on the PDA

Workspaces 60G
A workspace GOG is a container document that may be directly edited. A
workspace GOG contains links to project documents G10, displayed graphically on the workspace GOG surface, including 2D drawings, 3D models, images, notebooks, word documents, spreadsheets, etc. FIG. 7 illustrates multiple documents/files on a project G04 workspace GOG in accordance with one or more embodiments of the invention. The key function of the workspace GOG is to allow a user to organize documents G10 visually. A user can place documents G10 side by side for reference, or superimpose them like tracing paper.
A user can create any number of workspaces GOG. Each workspace GOG may have its own URL. The state of each workspace GOG is persistent such that when the user returns to a particular workspace GOG, the documents G10 the user was working on in the workspace GOG will be opened in the position that the user left them.
Documents 610 Referring to FIG. 7, the actual data that a user creates, edits and views is contained in documents. A user can access one or more documents by placing the desired document on a workspace 606. Examples of such documents include 2D
drawings 700, 702, and 704, 3D models 704, images, notebooks, word processing documents, spreadsheets, videos, audio recordings, digital photographs, or any other type of multimedia document. As illustrated in FIG. 7, numerous view of the same model/drawing may be displayed simultaneously. For example, view 706 illustrates a side elevation view of model 704. View 700 also illustrates a top view of the same model. Further, FIG. 7 illustrates the creation/modification of a document in a workspace. For example, a user may identify a point on a wall or ceiling of model 704, and drag the point up to raise/lower the ceiling. Various shapes and tools may be used to work with documents as described below.
The same documents can be opened in more than one workspace 606 at the same time. If both users have edit permission, both may edit the document at the same time.
Accordingly, referring back to FIG. 6, documents 610 contain the actual project 604 data, including designs, construction drawings, specifications, etc. The goal is to provide access to the data contained in the document 610 as immediate and direct as possible. Borders and widgets framing a document 610 may be minimized.
Further, tool actions apply to whichever document G10 is under the tool.
Every document 610 in the workspace 606 may have a title bar at the bottom that shows the document 610 name and contains icons for document 610 related commands. A user may drag a document 610 by the document's 610 title bar to reposition the document 610 in the workspace 606. A document 610 may also be resized by dragging a corner or edge. Such a resizing may enlarge a document's size without scaling an image in the document. Dragging by a graphically differentiated corner of the document 610 may resize the document 610 and scale or zoom its contents at the same time.
Document 610 related commands are accessed through icons on the title bar or a pop-up menu accessible through the document's 610 tide bar. Such commands may include "Close document", "Minimize", "Print", "Export", "Send", "Cut", "Copy", and "Paste". A document 610 title bar may also contain special commands that only appear for a certain type of document 610, e.g. "Forward" and "Back"
for a web document 610 or "Layers" for a layer stack.
Documents 610 may interact with and be layered on top of each other. In one or more embodiments, Studiodesk'"~f defines interfaces for each document that allows the document 610 to retrieve information from another document 610.
Such retrieved information may include a scale that allows documents 610 to scale appropriately to each other, an origin that allows documents 610 to be positioned so that their contents align correctly, and geometric snap information that allows geometry being drawn in a document 610 to snap to geometry in another document 610 under the first document 610.

Other document properties that may be viewed and/or edited may include Tide, Author, Creation Date, Color, Transparency, Scale, Grid Resolution, etc. Such properties may be edited using a property sheet accessible from a document 610 pop-up menu (or possibly from an icon on the title bar).
Various document 610 types may provide different functions and capabilities to a user. In accordance with one or more embodiments of the invention, the following document 610 types may be utilized:
(1) 2D paper - A document 610 used for creating and modifying. two dimensional (2D) drawings (e.g., a sketch, hardline, etc.). Properties for 2D
paper may include a variable transparency, scaling capabilities, zoom capabilities, resizing capabilities (e.g., by dragging a vertical or horizontal edge to add more paper), resealing capabilities (e.g., by dragging a corner to re-scale/resize the drawing), and importation capabilities (e.g., DWG files may be imported into the virtual desktop 900 drawing format).
(2) 3D modeling sheet - A document 610 type used for creating and modifying three dimensional (3D) models. Multiple 2D and 3D views may be shown/viewed at the same time.
(3) Notebook 912- A document 610 type that provides a container for workspaces 606 that allows a user to flip through the workspaces 606 similar to pages of a notebook. Since each page of the notebook 912 may comprise a workspace 606, the notebook 912 may contain any combination ox arrangement of documents 610.
(4) Layer stack - A document 610 type that provides a container for workspaces 606. A layer stack is similar to a notebook 912, but the pages may be transparent. A layer stack may be used to create the equivalent of a layered drawing.
Since each layer is a workspace 606, the layer stack may contain any combination or arrangement of documents. A layer stack may also be referred to as a container or composite document 610. As described, such a composite document 610 may provide for graphically associating multiple documents of various document/media types. Further, such a composite document 610 may be moved between two or more workspaces 606 as a unit using a graphical user interface.
(5) Other workspace 606 - A document 610 type that provides a graphical link from one workspace 606 to another workspace 606.
(6) Web page - A document 610 type that may be viewed in-place on the workspace 606 via a browser 208 of FIG. 2. A web page may provide basic web-browsing commands in a title bar.
(7) Non-native documents 610 - A document 610 type that represents documents 610 created in a foreign program (e.g. Word, Excel, etc.). A non-native document 610 may be viewed in the virtual desktop 900. Editing may be similar to embedded or container objects provided using component object model (COIVI) or object linking and embedding (OLE) technology. For example, when a user selects/clicks "Open" or double-clicks the document 610, the appropriate application opens in its own window.
Archives 608 When a document 610 is ftxst created in a workspace 606, it may only be accessible through that workspace 606. If a user deletes that workspace 606 from the project 604, the document 610 may also be deleted. A warning message may be displayed informing the user of the deletion of the document 610.
For longer term storage, a user can place documents 610 in an archive 608, that lets the user organize documents 610 hierarchically in folders. Once a document 610 is placed in an archive 608, the document 610 continues to exist in the project 604 even if the document 610 is not open in any workspace 606.
Subsequently, if a user places an archived document 610 back into a workspace 606, the document 610 as it appears in the workspace 606 is a link to the document 610 in the archive 608, and any edits the user makes apply to the original archived document 610. A user can explicitly create a new copy of a document if the user doesri t want to modify the original, or the user can open a document 610 read-only so that it can't be modified. An archived document 610 can be opened on more than one workspace 606 at a time. The archive may provide check in/check out, vexsioning, history, and other standard document management functions.
Web Site Embodiments To access project 604 documents 610, a user may first enter a portal web site 602. However, the user can also start the application by clicking on an icon on a PC
desktop without going to a web site. In addition to providing access to a user's project 604 documents 610, the web site 602 may contain a wide range of information related to digital design.
A user may navigate to a page containing a list of projects 604 in which the user is a participant. Each project 604 may be represented by a thumbnail image.
Clicking on a project 604 may bring up that project 604 on the virtual desktop.
Normally, projects 604 will have access control and a user will be asked to enter a username and password. This login may be the same for all projects 604 and may only have to ~be entered once per session. Subsequent to login, the web site of FIG.
Archives 608 When a document 610 is ftxst created in a workspace 606, it may only be accessible through that workspace 606. If a user deletes that workspace 606 from the project 604, the document 610 may also be deleted. A warning message may be displayed informing the user of the deletion of the document 610.
For longer term storage, a user can place documents 610 in an archive 608, that lets the user organize documents 610 hierarchically in folders. Once a document 610 is placed in an archive 608, the document 610 continues to exist in the project 604 even if the document 610 is not open in any workspace 606.
Subsequently, if a user places an archived document 610 back into a workspace 606, the document 610 as it appears in the workspace 606 is a link to the document 610 in the archive 608, and any edits the user makes apply to the original archived document 610. A user can explicitly create a new copy of a document if the user doesri t want to modify the original, or the user can open a document 610 read-only so that it can't be modified. An archived document 610 can be opened on more than one workspace 606 at a time. The archive may provide check in/check out, vexsioning, history, and other standard document management functions.
Web Site Embodiments To access project 604 documents 610, a user may first enter a portal web site 602. However, the user can also start the application by clicking on an icon on a PC
desktop without going to a web site. In addition to providing access to a user's project 604 documents 610, the web site 602 may contain a wide range of information related to digital design.
A user may navigate to a page containing a list of projects 604 in which the user is a participant. Each project 604 may be represented by a thumbnail image.
Clicking on a project 604 may bring up that project 604 on the virtual desktop.
Normally, projects 604 will have access control and a user will be asked to enter a username and password. This login may be the same for all projects 604 and may only have to ~be entered once per session. Subsequent to login, the web site of FIG.
8 may be displayed. FIG. 8 illustrates a mockup of project 604 listings in accordance with one or more embodiments of the invention. The web site of FIG. 8 may allow the user to select one of the projects 604 in a user's account.
When a user clicks on a project 604 on the web site, a virtual desktop will start up inside a browsex 208 window of FIG. 2. FIG. 9 illustrates the basic components of an architectural environment/virtual desktop 900 in accordance with one or more embodiments of the invention. The virtual desktop 900 gives the user a graphical view into a project's documents 610, along with tools to create, edit and view the documents 610. Menus 902, tool palettes 904, color editors 906, and property editors 908 surround a large workspace 606. Documents 610 displayed in the workspace 606 contain project data.
Further, as described above, when connected to the Internet or web site 602, multiple users may access and edit worskspaces 606 and documents 610 simultaneously. For example, multiple users at different locations may access and edit a workspace 606 or document 610 at the same time, while seeing each other's edits as they are made.
Tools Tools are objects that a user can use to create and edit project documents 610. Tools may include objects such as pens, erasers, rulers, etc.
Tools may be provided that function to reduce the complexity of a user interface. Accordingly, instead of presenting the user with a large fixed set of tools covering all the tasks a user might possibly want to accomplish, a set of tools tailored to a user's specific tasks may be assembled. When a user first opens a virtual desktop 900 or workspace 606, the workspace 606 may contain only a few basic tools that may be provided in a tool palette 904.
A user can add more tools by clicking on a "More Tools" command in a "Tools" menu 902 that may provide a user with an on-line catalog of tools.
Using the catalog, a user may drag and drop a new tool into the virtual desktop 900 (or the virtual desktop toolbar), workspace 606, or tool palette 904 and start using the new tool immediately.
FIG. 10 illustrates the addition of a tool from a web site. Web site 1000 contains multiple tools that may be selected. To utilize a tool from web site 1000, the user merely selects a tool such as ruler tool 1002 (that assists a user in drawing a line and displays a unit of measure (e.g., inches)), drags the selected tool to the toolbar (also referred to as tool palette 904) and drops the tool on the tool palette (e.g., ruler tool 1004 on the toolbar).
Tools are objects and have properties. For example, a pen may have a color and line weight. Referring back to FIG. 9, a user may change the pen color using a color control 906. A user can also create additional instances of a tool by copying it.
For example, if a user's work involves moving between a red, blue, and black pen frequently, a user can make two additional copies of a black pen tool and set their colors to be red and blue.
Tools maintain their functionality and work across documents 610. For example, a pen tool will draw a 2D stroke on a 2D drawing document 610. The same pen will draw onto the surface of a 3D model, or onto a 3D workplane. The data created by the tool depends on the context in which it is used, i.e., what the pen is drawing on.
Tools are placed on a tool palette 904. Tools can be placed anywhere on the palette 904, simply by dragging and dropping them. A user can stretch the palette 904 to accommodate new tools. The palette 904 can also be sized so that only a portion of the tools axe visible, in which case forward and backward buttons allow the user to quickly navigate through the tools on the palette 904. There can be multiple tool palettes 904. New tool palettes 904 may be created by the user as needed. Tools can be copied and moved between palettes 904.
Tools may not need to be placed on the palette 904 prior to use.
Additionally, objects instead of tools may be utilized to provide various elements of a document 610. For example, a wall object, window object, sunroof object, plant object, etc. may be placed and utilized in a document 610.
FIG. 11 illustrates the real time retrieval and use of an object in accordance with one or more embodiments of the invention. The user may browse to a web page that has various objects available such as door object 1100. As illustrated in FIG. 11, a door manufacturer may maintain a web site with various doors that are offered by the manufacturer. As provided by the manufacturer, the online representations of the doors may be objects with properties that enable the door to be used. A user merely selects door object 1100, drags the door object to the appropriate location, and drops the door on the drawing/model. Based on the properties, the window may be reoriented (as in door 1102) so that it accurately reflects the placement in the model or drawing. Alternatively, the door may be dropped onto the toolbar for additional use.
r~re~"" nno Referring back to FIG. 9, a menu bar 902 across the top of the virtual desktop 900 contains drop-down menus. The drop-down menus contain commands.
Unlike tools, commands may be modeless, one-shot operations, often applied to a selected object. The menus 902 are customizable, and new commands may be plugged in. The menu bar 902 can be positioned anywhere on the desktop by the user.
The following table illustrates the menu and drop-down menus that may be available:

Examples include color, name, transparency, width, etc. Tools, documents 610, geometric entities, etc. all have properties 908.
Commonly used properties 908 like color, pen width and transparency may be edited using special purpose controls (e.g., color window 906) that float over the workspace 606. Property 908 controls may also be accessible from a properties sheet, that may also float over the workspace 606.
Property sheets show the properties of an active tool. Additionally, if the active tool is the selector tool, the property sheet may display the properties of a selected object.
Project Navigation While using embodiments of the invention at a particular workspace 606, users may need access to other parts of a project, including other documents 610 or other workspaces 606. Accordingly, embodiments of the invention may provide several tools (e.g., a project navigator 910) fox navigating the project hierarchy. Such tools may display both textual information and graphical thumbnails.
Proylect Browser Fox general access to an entire project hierarchy, a project browser window may show a tree view of the project. A user may access all workspaces 606, archives, and documents 610 using this view. A user may also navigate to any project in which the user is a participant.
Workspace 606 Browser For quick access to a user's workspaces G06, a workspace 606 browser window may show a scrollable list of all of a user's workspaces 606 (across all projects). The user may select/click on a workspace 606 in this list to jump directly to that workspace 60G.
Archives Browsex Fox access to documents 610 in the archives for a current project, an archives browsex window may show a hierarchical view of an archive. A user may drag and drop documents 610 from one ox more archives to the workspace 606 to edit or view them. Additionally, a user may drag and drop documents 610 from the workspace 606 to the archives to store them.
Direct Viewing of Project Folders The desktop can view a project folder 604 as well as a workspace 606. A
project folder 604 may show icons and thumbnail images representing the folder and S workspaces 606 contained in that folder 604. Clicking on an icon or thumbnail may open that folder 604 or workspace 606 for viewing and editing. In addition to containing icons and thumbnails, a folder 604 view can also be drawn into and otherwise modified just like a workspace 606. Options may be provided for organizing icons and thumbnails into various arrangements: alphabetical, by date, etc.
Virtual Notebook One or more embodiments of the invention provide for a virtual designer's notebook that floats above the virtual desktop 900. FIG. 12 illustrates the use of such a virtual notebook 1200. A user can drag and drop data in both directions between the virtual notebook 1200 and the virtual desktop 900. For example, as illustrated in FIG. 12, a user can drag the document 1202 from the virtual desktop 900 and drop the document to the virtual notebook 1200. A user can use a virtual notebook 1200 similar to a graphical clipboard when browsing for data or when transferring data or documents between workspaces 606. Each page in the notebook 1200 is a workspace 606 document and can contain any data that can exist in/on a virtual desktop 900 or an environment provided in accordance with one or more embodiments of the invention. Another workspace 606 may be examined by selecting a virtual button 1204 that moves to the next workspace 606 in the notebook 1200.
A virtual notebook 1200 may run on any operating system available for hand held computing devices (PDAs) such as the Pahn OS or Windows CE. If a palm device is synchronized to the desktop 900, the contents of the virtual notebook 1200 on the desktop 900 will be synchronized with the virtual notebook 1200 on the palm device.
The virtual notebook 1200 is a separate application that runs on a user's desktop independently of other applications. A virtual notebook 1200 can be used as a graphical clipboard for data from other applications (e.g., Word, Excel, etc.).
Further, available tools (as described above) may be utilized in the virtual notebook 1200.
Drawing and Sketching A user can create drawings using pens of various types, colors and widths. A
flood fill and eraser tool may also aid in the drawing process. Such tools may be used freehand to create sketches.
A user can use available tools to create hard-line drawings, along with a stencil, that allows a user to constrain a tool to create a specific hard-line geometry (e.g., a straight line, rectangle, or circle). Stencils may also be used to create symbols such as a door, outlet, or sprinkler head. Geometry created using stencils may create an object that maintains properties (e.g., width, height, radius, etc.).
Further, the objects and properties may be selected and edited. Objects may also be dragged and dropped to and from a notebook (e.g., virtual notebook 1200). Accordingly, notebooks may act as catalogs for organizing larger collections of predefined content.
A user may add a text block to a drawing using a text tool. A text block can be selected and edited in place or in a text editing dialog. Usual text formats may be supported such as font, font size, font style, word wrap, etc. Text may also be input using mechanisms available such as a physical keyboard, a virtual keyboard, and/or using handwriting recognition.
Drafting Drafting is not fundamentally different from the sketching and hard-line drawing described above. Accordingly, additional tools and options to address the need for precision and efficiency in drafting may be provided.
Scale 2D drawing documents may have a scale property that is an internal representation of the scale of a document (e.g., 1/8 inch = 1 foot). Further, a scale tool provides the ability to set the scale property by identifying a distance using an input device (e.g., drawing a line) and specifying a unit of measurement represented by the distance (e.g., 1 foot). Additionally, adjusting the scaling may modify the internal scale representation of the document without modifying the actual size of the document.
Sna Support snapping to endpoints, midpoints and other geometric locations, as well as snapping perpendicular and tangent may be available.
Drawing tools Additional drawing tools, including trim, extend and offset may also be provided.
Precision and Numerical Input A mechanism for efficiently defining geometry by entering or measuring out exact numeric values may be available. This may consist of a ruler-like graphic that is displayed while drawing lines or other geometry, which will display the current length and angle of the geometry as it is drawn. Typing while the ruler is displayed may set the length or angle directly for the geometry. The ruler extends beyond the current geometry in order to give visual feedback about available length values taking into account the drawing scale.
Dimensioning Tools for creating dimensions may also be provided. Dimensions are objects that snap to geometry and may be associative.
Layers Layered drawings are created using layer stacks. A layer stack is a collection of transparent workspaces 606 superimposed and registered for alignment. A
layer stack provides access to various sheets in a stack using a list of the layers.
A user can make a given layer active by selecting the desired layer in this list. The order in the list determines the order of layers in the stack, and thus the draw order.
Layers do not determine color or other properties. All layers in the stack may have the same drawing scale by default.
Predefined drawing objects Predefined drawing objects may allow the user to add pre-drawn objects to a drawing. Such objects may be similar to ACTIVESHAPESTM, with plugs, sockets, and sizing handles. However, predefined drawing objects may not have expressions and may not be programmable. Pre-defined objects may also be dragged and dropped from web-based catalogs.
3D Modeling A feature-based solid modeler for use in creating study models as well as more formal simulations or presentation models may be provided. The user-interface for modeling may be specifically tailored to the requirements of architectural models. One basic approach provides for the creation of sheets or blocks of material by drawing outlines in 2D and pulling the 2D outlines into 3D.
Sheets are analogous to cardboard or foam-core-type materials and blocks are analogous to wood or clay. These materials can then be modified by cutting them with a knife tool or by extracting material using a xouter tool. Features created by cutting can be selected and positioned. Snapping and collision detection are active during model creation and editing to aid in creating precise geometric relationships.
Modeling may be performed in a document referred to as a modeling sheet.
A modeling sheet document contains the model geometry and provides various projections of a model, including plan, elevation, axonometric, and perspective. A
model may not have a separate existence outside of the modeling sheet document.
The contents of a 2D drawing document may also be rotated into 3D. The 2D geometry will appear on the ground plane in the 3D view. 3D modeling data can then be added using the 2D drawing as a reference. The 2D geometry, including lines, rectangles, circles, etc., may also be directly extruded upwards to create 3D
shapes.
2D projections of the model such as elevation or plan may be rendered fully shaded or as line drawings. 3D projections like axonometric or perspective are rendered using shading that is realistic to the extent necessary to convey an immediate sense of geometric and spatial relationships. This level of rendering may include soft shadows, gradations of light across flat surfaces and realistic ambient lighting. Antialiasing may also be supported.
3D modeling may also include the ability to apply texture maps to surfaces and to select and manipulate texture maps and/or surfaces as objects. A user may drag a texture map around on a surface and resize the texture map interactively using handles (as described above with respect to FIG. 7). Textures may be tiled to cover the entire surface or act as decals.
3D geometry provides basic material properties that may include color, transparency, and shininess. Properties may be applied to the entire model geometry, and not to individual faces. Further, changes to surface properties may be updated dynamically.
When drawing tools such as pencils or markers are used over a 3D surface, the tool will draw onto the surface in 3D.
Several different types of camera tools may be provided for modifying 3D
views interactively, including a simple lazy-susan type orbit tool, an unconstrained orbit tool, and walk or fly through tools.
Non-Graphical Data To fully specify a building, geometric representations in drawings may be linked to specification data, including textual descriptions, manufacturers data, etc.
Such data may then be extracted from a project database by downstream applications fox bidding or facilities management. For example, door and window schedules can be generated automatically.
A tag property for geometric objects like lines may be available. Such a tag is a link to a record in another project document, which contains the additional data describing the object.
Special tools may be used to create special purpose types of tagged geometry.
For example, a tool for drawing polylines that creates a geometrical shape linked by a tag to a pre-selected material type (e.g., a brick wall) can be used to determine the quantity of material needed (referred to as a quantity take of~ by tracing with the tool in a separate layer superimposed over a construction drawing.
Native spreadsheet document support may enable support for quantitative analysis. Simple tools may also be created for computing areas for quantity take offs, for example. FIG. 13 illustrates a virtual desktop 900 where numerical input is obtained from a drawing and utilized in a spreadsheet. Box 1300 is placed around an existing plan 1304. Based on the scale of the drawing, the square footage of the boxed area may be automatically obtained and input into spreadsheet program as a quantity 1302. The spreadsheet program may then utilize the quantity 1302 for calculations such as flooring cost.
Links are bi-directional so a change to the source description may be followed back to all of the instances in the various drawings, to make sure changes do not introduce errors or inconsistencies.
Annotation and Markup Referring back to FIG. 6, a user may annotate any document 610 using a special annotation pen and eraser or by drawing directly on a document 610 in an annotation layer. Annotations made with the annotation pen may be erased using an annotation eraser without affecting the original document 610 data (a pen tool may be used as an annotation tool by setting the pen tool's annotation property).
An annotation pen can add annotation to any document 610 viewable on the workspace 606, even those for which the user doesn't have write access. If a user doesri t have write access to a document 610 or if pen strokes axe not supported by the document 610 (e.g. an image or a Word document 610), any pen that the user uses on the document 610 will act as an annotation pen. Annotation may create stroke data.
Other types of data (bitmap, 3D, text) may not be a permissible mechanism for creating annotation. Further, if desirable, the workspace 606 itself may be used as the container for the markup.
Annotations may conceptually be part of a document 610 and travel or attach to the document 610. Thereafter, when a user copies a document 610, annotations may be included. Further, when such a document 610 is copied or archived, the annotations may also be included. For example, a word processing document 610 with annotation may be presented as a single document 610.
If a user emails a document outside of an application (e.g., a site 602, project 604, workspace 606, etc.), the user may have the choice of flattening the document 610. For example, if an image document 610 is flattened, annotations associated with the image may become part of the actual image data. In another example, annotation on a word processing document 610 may be converted to word processing data when the word processing document is flattened.
Any document 610 may be annotated, even documents 610 for which the user does not have write access. To provide such annotation capabilities, one or more of the following options may be utilized:
(1) special annotation tools;
(2) a transparent annotation layer for all documents 610;
(3) only documents 610 that have been flattened into read-only bitmaps (like marking up a copy) can be annotated; and (4) annotation of a document 610 merely draws into the actual document 610 itself (all documents 610 may support strokes).
Administration and Access Control Ownership may be defined for a global list of users. Such a list may comprise user names, passwords, and tags (e.g., group membership, role). Additionally, projects 604 may include a list of users with additional properties added (e.g., a "principal" property).
Certificates as an option may also be supported. Further, access control lists (ACLs) (a set of data associated with a file, directory or other resource that defines the permissions that users and/or groups have for accessing it) may be provided on a per-project 604 and/or per-document 610 basis. Additionally, two people with write-access may have the ability to edit the same document 610 at the same time.
Personal Digital Assistant (PDALpport FIG. 14 illustrates a PDA in accordance with one or more embodiments of the invention. A tablet may provide a PDA (such as PDA 1400 of FIG. 14) as a pen input device (referred to as a pen tablet) for an application running on a client.
Accordingly, a standard PDA may be used as a pen tablet. By providing such capabilities, persons who do not have a pen tablet axe provided with the opportunity to try a pen tablet type of application. Thus, the pen tablet may provide exposure of the invention to a much wider group of people and users.
A user may run a pen tablet when a PDA is plugged into a PC (or Macintosh) running an application. The PDA screen is mapped to a 160x160 area on a display area of the PC. A user can move this area by dragging the area with an input device such as a mouse or by using a pan tool on the PDA. Data within the mapped area on the PC will appear in the PDA screen as a non-editable background.
Conversely, strokes drawn on the PDA will be drawn on the PC within the mapped area. A PDA
may provide a thick and thin pen.
A notebook may provide the user of a PDA 1400 with an off line designer's notebook. FIG. 14 illustrates the notebook or virtual desktop 900 on a PDA
1400.
A notebook as referred to herein is a multi-page notebook that the user can load with images and drawings from the application on the PC, then work off line with them on a PDA 1400, using them for reference and annotating them using a selection of basic drawing tools. The user can also create sketches and drawings in the notebook.
Annotations and drawings created off line can be uploaded and synchronized with a PC when the PDA is connected to (or communicates with) the PC. The PDA
synchronizes with a virtual PDA floating on the PC desktop. Data may then be transferred between the virtual PDA to and from the virtual desktop 900 using drag and drop. Further, the virtual PDA on the desktop 900 may be used independently of the PDA.
Screen Capture A user may capture images of other documents on a PC desktop. For example, a user may have a drawing file in another application (e.g., AutoCAD) that the user wishes to annotate, mark-up, ox refer to. In some cases, such a ftle may be imported directly. However, such importation may consume valuable system resources. Further, the user may merely require a snapshot of data currently visible on the screen.
Two approaches may be utilized for screen capture operations as follows:
(1) Transparent Browser A transparent browser provides the ability to see-through a screen (i.e., provides a transparency). A slider controls the transparency of the workspace itself.
When transparent, a user can see through the browser onto the data or document located behind the browser on the desktop 900. Further, a user can capture the information/data visible through the browser and add it to the workspace as a bitmap image (e.g., by clicking a button). A captured image may then be annotated using the normal annotation tools. FIG. 15 illustrates a transparent browser provided in accordance with one or more embodiments of the invention. Window 1502 can be viewed through transparent bxowser 1500. Further, the image in window 1502 may be captured and the user can annotate 1504 the captured image.
(2) Screen capture utility A stand-alone utility may allow a user to capture any area of a virtual desktop and insert it as a bitmap into a workspace. When a user clicks on a "Capture"
command, the workspace mir~irruzes and the cursor changes to a capture cursor.
The user may then define/designate an area to be captured (e.g., by dragging out a rectangle). Once an area has been defined, the defined area may be automatically captured and inserted into the workspace as a bitmap image. This image may then be annotated and otherwise manipulated, similar to any other bitmap image document.
Conclusion This concludes the description of one or more embodiments of the invention. The following describes some alternative embodiments fox accomplishing the present invention without departing from the scope of the present invention.
For example, any type of computer, such as a mainframe, minicomputer, workstation or personal computer, could be used with the present invention. In addition, any software program, application or operating system having a user interface could benefit from the present invention.
The foregoing description of one ox more embodiments of the invention has been presented for the purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed. Many modifications and variations axe possible in light of the above teaching. It is intended that the scope of the invention be limited not by this detailed description, but rather by the claims appended hereto.
When a user clicks on a project 604 on the web site, a virtual desktop will start up inside a browsex 208 window of FIG. 2. FIG. 9 illustrates the basic components of an architectural environment/virtual desktop 900 in accordance with one or more embodiments of the invention. The virtual desktop 900 gives the user a graphical view into a project's documents 610, along with tools to create, edit and view the documents 610. Menus 902, tool palettes 904, color editors 906, and property editors 908 surround a large workspace 606. Documents 610 displayed in the workspace 606 contain project data.
Further, as described above, when connected to the Internet or web site 602, multiple users may access and edit worskspaces 606 and documents 610 simultaneously. For example, multiple users at different locations may access and edit a workspace 606 or document 610 at the same time, while seeing each other's edits as they are made.
Tools Tools are objects that a user can use to create and edit project documents 610. Tools may include objects such as pens, erasers, rulers, etc.
Tools may be provided that function to reduce the complexity of a user interface. Accordingly, instead of presenting the user with a large fixed set of tools covering all the tasks a user might possibly want to accomplish, a set of tools tailored to a user's specific tasks may be assembled. When a user first opens a virtual desktop 900 or workspace 606, the workspace 606 may contain only a few basic tools that may be provided in a tool palette 904.
A user can add more tools by clicking on a "More Tools" command in a "Tools" menu 902 that may provide a user with an on-line catalog of tools.
Using the catalog, a user may drag and drop a new tool into the virtual desktop 900 (or the virtual desktop toolbar), workspace 606, or tool palette 904 and start using the new tool immediately.
FIG. 10 illustrates the addition of a tool from a web site. Web site 1000 contains multiple tools that may be selected. To utilize a tool from web site 1000, the user merely selects a tool such as ruler tool 1002 (that assists a user in drawing a line and displays a unit of measure (e.g., inches)), drags the selected tool to the toolbar (also referred to as tool palette 904) and drops the tool on the tool palette (e.g., ruler tool 1004 on the toolbar).
Tools are objects and have properties. For example, a pen may have a color and line weight. Referring back to FIG. 9, a user may change the pen color using a color control 906. A user can also create additional instances of a tool by copying it.
For example, if a user's work involves moving between a red, blue, and black pen frequently, a user can make two additional copies of a black pen tool and set their colors to be red and blue.
Tools maintain their functionality and work across documents 610. For example, a pen tool will draw a 2D stroke on a 2D drawing document 610. The same pen will draw onto the surface of a 3D model, or onto a 3D workplane. The data created by the tool depends on the context in which it is used, i.e., what the pen is drawing on.
Tools are placed on a tool palette 904. Tools can be placed anywhere on the palette 904, simply by dragging and dropping them. A user can stretch the palette 904 to accommodate new tools. The palette 904 can also be sized so that only a portion of the tools axe visible, in which case forward and backward buttons allow the user to quickly navigate through the tools on the palette 904. There can be multiple tool palettes 904. New tool palettes 904 may be created by the user as needed. Tools can be copied and moved between palettes 904.
Tools may not need to be placed on the palette 904 prior to use.
Additionally, objects instead of tools may be utilized to provide various elements of a document 610. For example, a wall object, window object, sunroof object, plant object, etc. may be placed and utilized in a document 610.
FIG. 11 illustrates the real time retrieval and use of an object in accordance with one or more embodiments of the invention. The user may browse to a web page that has various objects available such as door object 1100. As illustrated in FIG. 11, a door manufacturer may maintain a web site with various doors that are offered by the manufacturer. As provided by the manufacturer, the online representations of the doors may be objects with properties that enable the door to be used. A user merely selects door object 1100, drags the door object to the appropriate location, and drops the door on the drawing/model. Based on the properties, the window may be reoriented (as in door 1102) so that it accurately reflects the placement in the model or drawing. Alternatively, the door may be dropped onto the toolbar for additional use.
r~re~"" nno Referring back to FIG. 9, a menu bar 902 across the top of the virtual desktop 900 contains drop-down menus. The drop-down menus contain commands.
Unlike tools, commands may be modeless, one-shot operations, often applied to a selected object. The menus 902 are customizable, and new commands may be plugged in. The menu bar 902 can be positioned anywhere on the desktop by the user.

Additionally, a user may drag and drop documents 610 from the workspace 606 to the archives to store them.
Direct Viewing of Project Folders The desktop can view a project folder 604 as well as a workspace 606. A
project folder 604 may show icons and thumbnail images representing the folder and S workspaces 606 contained in that folder 604. Clicking on an icon or thumbnail may open that folder 604 or workspace 606 for viewing and editing. In addition to containing icons and thumbnails, a folder 604 view can also be drawn into and otherwise modified just like a workspace 606. Options may be provided for organizing icons and thumbnails into various arrangements: alphabetical, by date, etc.
Virtual Notebook One or more embodiments of the invention provide for a virtual designer's notebook that floats above the virtual desktop 900. FIG. 12 illustrates the use of such a virtual notebook 1200. A user can drag and drop data in both directions between the virtual notebook 1200 and the virtual desktop 900. For example, as illustrated in FIG. 12, a user can drag the document 1202 from the virtual desktop 900 and drop the document to the virtual notebook 1200. A user can use a virtual notebook 1200 similar to a graphical clipboard when browsing for data or when transferring data or documents between workspaces 606. Each page in the notebook 1200 is a workspace 606 document and can contain any data that can exist in/on a virtual desktop 900 or an environment provided in accordance with one or more embodiments of the invention. Another workspace 606 may be examined by selecting a virtual button 1204 that moves to the next workspace 606 in the notebook 1200.
A virtual notebook 1200 may run on any operating system available for hand held computing devices (PDAs) such as the Pahn OS or Windows CE. If a palm device is synchronized to the desktop 900, the contents of the virtual notebook 1200 on the desktop 900 will be synchronized with the virtual notebook 1200 on the palm device.
The virtual notebook 1200 is a separate application that runs on a user's desktop independently of other applications. A virtual notebook 1200 can be used as a graphical clipboard for data from other applications (e.g., Word, Excel, etc.).
Further, available tools (as described above) may be utilized in the virtual notebook 1200.
Drawing and Sketching A user can create drawings using pens of various types, colors and widths. A
flood fill and eraser tool may also aid in the drawing process. Such tools may be used freehand to create sketches.
A user can use available tools to create hard-line drawings, along with a stencil, that allows a user to constrain a tool to create a specific hard-line geometry (e.g., a straight line, rectangle, or circle). Stencils may also be used to create symbols such as a door, outlet, or sprinkler head. Geometry created using stencils may create an object that maintains properties (e.g., width, height, radius, etc.).
Further, the objects and properties may be selected and edited. Objects may also be dragged and dropped to and from a notebook (e.g., virtual notebook 1200). Accordingly, notebooks may act as catalogs for organizing larger collections of predefined content.
A user may add a text block to a drawing using a text tool. A text block can be selected and edited in place or in a text editing dialog. Usual text formats may be supported such as font, font size, font style, word wrap, etc. Text may also be input using mechanisms available such as a physical keyboard, a virtual keyboard, and/or using handwriting recognition.
Drafting Drafting is not fundamentally different from the sketching and hard-line drawing described above. Accordingly, additional tools and options to address the need for precision and efficiency in drafting may be provided.
Scale 2D drawing documents may have a scale property that is an internal representation of the scale of a document (e.g., 1/8 inch = 1 foot). Further, a scale tool provides the ability to set the scale property by identifying a distance using an input device (e.g., drawing a line) and specifying a unit of measurement represented by the distance (e.g., 1 foot). Additionally, adjusting the scaling may modify the internal scale representation of the document without modifying the actual size of the document.
Sna Support snapping to endpoints, midpoints and other geometric locations, as well as snapping perpendicular and tangent may be available.
Drawing tools Additional drawing tools, including trim, extend and offset may also be provided.
Precision and Numerical Input A mechanism for efficiently defining geometry by entering or measuring out exact numeric values may be available. This may consist of a ruler-like graphic that is displayed while drawing lines or other geometry, which will display the current length and angle of the geometry as it is drawn. Typing while the ruler is displayed may set the length or angle directly for the geometry. The ruler extends beyond the current geometry in order to give visual feedback about available length values taking into account the drawing scale.
Dimensioning Tools for creating dimensions may also be provided. Dimensions are objects that snap to geometry and may be associative.
Layers Layered drawings are created using layer stacks. A layer stack is a collection of transparent workspaces 606 superimposed and registered for alignment. A
layer stack provides access to various sheets in a stack using a list of the layers.
A user can make a given layer active by selecting the desired layer in this list. The order in the list determines the order of layers in the stack, and thus the draw order.
Layers do not determine color or other properties. All layers in the stack may have the same drawing scale by default.
Predefined drawing objects Predefined drawing objects may allow the user to add pre-drawn objects to a drawing. Such objects may be similar to ACTIVESHAPESTM, with plugs, sockets, and sizing handles. However, predefined drawing objects may not have expressions and may not be programmable. Pre-defined objects may also be dragged and dropped from web-based catalogs.
3D Modeling A feature-based solid modeler for use in creating study models as well as more formal simulations or presentation models may be provided. The user-interface for modeling may be specifically tailored to the requirements of architectural models. One basic approach provides for the creation of sheets or blocks of material by drawing outlines in 2D and pulling the 2D outlines into 3D.
Sheets are analogous to cardboard or foam-core-type materials and blocks are analogous to wood or clay. These materials can then be modified by cutting them with a knife tool or by extracting material using a xouter tool. Features created by cutting can be selected and positioned. Snapping and collision detection are active during model creation and editing to aid in creating precise geometric relationships.
Modeling may be performed in a document referred to as a modeling sheet.
A modeling sheet document contains the model geometry and provides various projections of a model, including plan, elevation, axonometric, and perspective. A
model may not have a separate existence outside of the modeling sheet document.
The contents of a 2D drawing document may also be rotated into 3D. The 2D geometry will appear on the ground plane in the 3D view. 3D modeling data can then be added using the 2D drawing as a reference. The 2D geometry, including lines, rectangles, circles, etc., may also be directly extruded upwards to create 3D
shapes.
2D projections of the model such as elevation or plan may be rendered fully shaded or as line drawings. 3D projections like axonometric or perspective are rendered using shading that is realistic to the extent necessary to convey an immediate sense of geometric and spatial relationships. This level of rendering may include soft shadows, gradations of light across flat surfaces and realistic ambient lighting. Antialiasing may also be supported.
3D modeling may also include the ability to apply texture maps to surfaces and to select and manipulate texture maps and/or surfaces as objects. A user may drag a texture map around on a surface and resize the texture map interactively using handles (as described above with respect to FIG. 7). Textures may be tiled to cover the entire surface or act as decals.
3D geometry provides basic material properties that may include color, transparency, and shininess. Properties may be applied to the entire model geometry, and not to individual faces. Further, changes to surface properties may be updated dynamically.
When drawing tools such as pencils or markers are used over a 3D surface, the tool will draw onto the surface in 3D.
Several different types of camera tools may be provided for modifying 3D
views interactively, including a simple lazy-susan type orbit tool, an unconstrained orbit tool, and walk or fly through tools.
Non-Graphical Data To fully specify a building, geometric representations in drawings may be linked to specification data, including textual descriptions, manufacturers data, etc.
Such data may then be extracted from a project database by downstream applications fox bidding or facilities management. For example, door and window schedules can be generated automatically.
A tag property for geometric objects like lines may be available. Such a tag is a link to a record in another project document, which contains the additional data describing the object.
Special tools may be used to create special purpose types of tagged geometry.
For example, a tool for drawing polylines that creates a geometrical shape linked by a tag to a pre-selected material type (e.g., a brick wall) can be used to determine the quantity of material needed (referred to as a quantity take of~ by tracing with the tool in a separate layer superimposed over a construction drawing.
Native spreadsheet document support may enable support for quantitative analysis. Simple tools may also be created for computing areas for quantity take offs, for example. FIG. 13 illustrates a virtual desktop 900 where numerical input is obtained from a drawing and utilized in a spreadsheet. Box 1300 is placed around an existing plan 1304. Based on the scale of the drawing, the square footage of the boxed area may be automatically obtained and input into spreadsheet program as a quantity 1302. The spreadsheet program may then utilize the quantity 1302 for calculations such as flooring cost.
Links are bi-directional so a change to the source description may be followed back to all of the instances in the various drawings, to make sure changes do not introduce errors or inconsistencies.
Annotation and Markup Referring back to FIG. 6, a user may annotate any document 610 using a special annotation pen and eraser or by drawing directly on a document 610 in an annotation layer. Annotations made with the annotation pen may be erased using an annotation eraser without affecting the original document 610 data (a pen tool may be used as an annotation tool by setting the pen tool's annotation property).
An annotation pen can add annotation to any document 610 viewable on the workspace 606, even those for which the user doesn't have write access. If a user doesri t have write access to a document 610 or if pen strokes axe not supported by the document 610 (e.g. an image or a Word document 610), any pen that the user uses on the document 610 will act as an annotation pen. Annotation may create stroke data.
Other types of data (bitmap, 3D, text) may not be a permissible mechanism for creating annotation. Further, if desirable, the workspace 606 itself may be used as the container for the markup.
Annotations may conceptually be part of a document 610 and travel or attach to the document 610. Thereafter, when a user copies a document 610, annotations may be included. Further, when such a document 610 is copied or archived, the annotations may also be included. For example, a word processing document 610 with annotation may be presented as a single document 610.
If a user emails a document outside of an application (e.g., a site 602, project 604, workspace 606, etc.), the user may have the choice of flattening the document 610. For example, if an image document 610 is flattened, annotations associated with the image may become part of the actual image data. In another example, annotation on a word processing document 610 may be converted to word processing data when the word processing document is flattened.
Any document 610 may be annotated, even documents 610 for which the user does not have write access. To provide such annotation capabilities, one or more of the following options may be utilized:
(1) special annotation tools;
(2) a transparent annotation layer for all documents 610;
(3) only documents 610 that have been flattened into read-only bitmaps (like marking up a copy) can be annotated; and (4) annotation of a document 610 merely draws into the actual document 610 itself (all documents 610 may support strokes).
Administration and Access Control Ownership may be defined for a global list of users. Such a list may comprise user names, passwords, and tags (e.g., group membership, role). Additionally, projects 604 may include a list of users with additional properties added (e.g., a "principal" property).
Certificates as an option may also be supported. Further, access control lists (ACLs) (a set of data associated with a file, directory or other resource that defines the permissions that users and/or groups have for accessing it) may be provided on a per-project 604 and/or per-document 610 basis. Additionally, two people with write-access may have the ability to edit the same document 610 at the same time.
Personal Digital Assistant (PDALpport FIG. 14 illustrates a PDA in accordance with one or more embodiments of the invention. A tablet may provide a PDA (such as PDA 1400 of FIG. 14) as a pen input device (referred to as a pen tablet) for an application running on a client.
Accordingly, a standard PDA may be used as a pen tablet. By providing such capabilities, persons who do not have a pen tablet axe provided with the opportunity to try a pen tablet type of application. Thus, the pen tablet may provide exposure of the invention to a much wider group of people and users.
A user may run a pen tablet when a PDA is plugged into a PC (or Macintosh) running an application. The PDA screen is mapped to a 160x160 area on a display area of the PC. A user can move this area by dragging the area with an input device such as a mouse or by using a pan tool on the PDA. Data within the mapped area on the PC will appear in the PDA screen as a non-editable background.
Conversely, strokes drawn on the PDA will be drawn on the PC within the mapped area. A PDA
may provide a thick and thin pen.
A notebook may provide the user of a PDA 1400 with an off line designer's notebook. FIG. 14 illustrates the notebook or virtual desktop 900 on a PDA
1400.
A notebook as referred to herein is a multi-page notebook that the user can load with images and drawings from the application on the PC, then work off line with them on a PDA 1400, using them for reference and annotating them using a selection of basic drawing tools. The user can also create sketches and drawings in the notebook.
Annotations and drawings created off line can be uploaded and synchronized with a PC when the PDA is connected to (or communicates with) the PC. The PDA
synchronizes with a virtual PDA floating on the PC desktop. Data may then be transferred between the virtual PDA to and from the virtual desktop 900 using drag and drop. Further, the virtual PDA on the desktop 900 may be used independently of the PDA.
Screen Capture A user may capture images of other documents on a PC desktop. For example, a user may have a drawing file in another application (e.g., AutoCAD) that the user wishes to annotate, mark-up, ox refer to. In some cases, such a ftle may be imported directly. However, such importation may consume valuable system resources. Further, the user may merely require a snapshot of data currently visible on the screen.
Two approaches may be utilized for screen capture operations as follows:
(1) Transparent Browser A transparent browser provides the ability to see-through a screen (i.e., provides a transparency). A slider controls the transparency of the workspace itself.
When transparent, a user can see through the browser onto the data or document located behind the browser on the desktop 900. Further, a user can capture the information/data visible through the browser and add it to the workspace as a bitmap image (e.g., by clicking a button). A captured image may then be annotated using the normal annotation tools. FIG. 15 illustrates a transparent browser provided in accordance with one or more embodiments of the invention. Window 1502 can be viewed through transparent bxowser 1500. Further, the image in window 1502 may be captured and the user can annotate 1504 the captured image.
(2) Screen capture utility A stand-alone utility may allow a user to capture any area of a virtual desktop and insert it as a bitmap into a workspace. When a user clicks on a "Capture"
command, the workspace mir~irruzes and the cursor changes to a capture cursor.
The user may then define/designate an area to be captured (e.g., by dragging out a rectangle). Once an area has been defined, the defined area may be automatically captured and inserted into the workspace as a bitmap image. This image may then be annotated and otherwise manipulated, similar to any other bitmap image document.
Conclusion This concludes the description of one or more embodiments of the invention. The following describes some alternative embodiments fox accomplishing the present invention without departing from the scope of the present invention.
For example, any type of computer, such as a mainframe, minicomputer, workstation or personal computer, could be used with the present invention. In addition, any software program, application or operating system having a user interface could benefit from the present invention.
The foregoing description of one ox more embodiments of the invention has been presented for the purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed. Many modifications and variations axe possible in light of the above teaching. It is intended that the scope of the invention be limited not by this detailed description, but rather by the claims appended hereto.
