How to access the new feature
Helpful hints and tips

DataCAD 11 is compatible with the same drawing files, symbols, templates, line types,hatch patterns, fonts, and DCAL macros,as DataCAD versions 4 through 10.

DataCAD's graphic pipeline has been enhanced for improved performance. The time required for Panning, Zooming, Dynamic Panning, and Scroll Wheel Zooming has been significantly reduced. In addition, the Perspective Walk Through, Pan View setting is recognized when you use either the scroll wheel or the dynamic panning method to walk forward or backward or step up, down, left, or right respectively. A new menu item, Scroll Dist., has been added to the Perspective, Walk Through, Options menu to set the walk and step distance when you use the mouse to navigate in a perspective view.

DataCAD 11 uses double-precision floating point math to calculate and store values in the drawing database. Prior versions of DataCAD had an effective accuracy of ~7 decimal places. DataCAD 11 has an effective accuracy of ~14 decimal places. That means DataCAD 11 is now as accurate as AutoCAD and you can work on much larger projects without running into rounding issues, especially when importing large drawings.

DataCAD can query other instances of DataCAD running on a network to determine whether or not a file is in-use. Every time you open a drawing, DataCAD records the date, time, username, and workstation name in a corresponding user (.U$R) file. If you try to open a drawing file that is in-use, DataCAD will only allow you to open a copy of the file.

We revamped DataCADs backup and recover process to be more reliable and intuitive. Whenever you exit a drawing abnormally, DataCAD will automatically try to recover the most recent version of your file without prompting you with unnecessary warnings and options.

DataCAD files are automatically purged of any unused data each time you exit and save your drawing. In addition, a Purge dialog replaces the Layer Utility macro, allowing you to create new drawings based on a sub-set of an existing drawing.


Purge Drawing Dialog

To access Purge Drawing options, select Purge... from the File menu.
Selecting saved views or multi-scale plotting sheets will automatically select corresponding layers.

DataCAD 11 drawings are now stored in a compressed format making them roughly 1/5 the size of previous versions.

Drawing session backups is a new feature that allows you to configure DataCAD to automatically save up to 10 incrementally-named backup drawings. Session backups are only created each time you exit and save your drawing.

To access Drawing Session options, go the Misc. tab of Program Preferences.
A new drawing session is created only when you close and save your drawing.
You can have a maximum of 10 drawing sessions per file.

DataCAD 11 features an updated program interface that provides Windows 2000-style properties and support for Windows XP Themes and "Skins". You can position toolbars and menus where you want by tearing them off and docking them to the top, bottom, left, or right side of the application window. You can also place toolbars and menus outside of DataCAD to "float" on the desktop, allowing you to resize the drawing area without adversely affecting the user interface and to take advantage of dual monitor displays. In addition, all of the interface elements in DataCAD 11 will inherit the visual style of your current desktop theme.

DataCAD 11 introduces an easier way to browse, select, and manage symbols. The new Symbol Browser allows you to rapidly find, place, customize, and manage symbols that you use in your drawings. Inserting a symbol into your drawing involves little more than selecting it from the Symbol Browser and dropping it where you want it. With just a few mouse clicks, you can open the appropriate folder, display the symbols in the browser, and select the ones you want to use into your drawing. If you developed custom templates with older versions of DataCAD, you can open them in the Symbol Browser, too. In effect, the Symbol Browser treats file folders as templates that contain collections of symbols.

To access the Symbol Browser, go to the View pull-down menu and select Symbol Browser.
You can use the [Ctrl] + [T] shortcut to open and close the Symbol Browser.

It's now possible to assign an unlimited number of user-defined fields to symbols for enhanced reporting. You're no longer limited to the five default fields.


Symbol Field Editor

To edit symbol fields, select Edit Fields from the Symbol Browser Options menu.

We've enhanced symbol reporting so you can run reports on all symbols in the drawing instead of just the symbols in the active template. A new dialog gives you access to report forms and displays an on-the-fly preview of the results.


Symbol Report Form Dialog

To access symbol reports, select Reports from the Symbol Browser Options menu.
You can run reports on any symbol you've placed in the drawing, not just the symbols displayed in the Symbol Browser.

Text attributes can be defined and added to symbols. This lets you use the same symbol multiple times, supplying a unique text string for each one. For example, you could use one desk symbol several times and label them Jim's desk, Nancy's desk, and Bob's desk.

To create a symbol attribute, go to the Text menu and select Sym Attrib.
A symbol can contain an unlimited number of attributes.

Text attributes can be defined and added to symbols. This lets you use the same symbol multiple times, supplying a unique text string for each one. For example, you could use one desk symbol several times and label them Jim's desk, Nancy's desk, and Bob's desk.

To access symbol text attribute reports, select the Extract Attributes option from the Symbol Browser Options menu.

A new option available for inserting symbols allows you to drop any item such as a symbol directly on the surface of a polygon.

To insert a symbol directly on to a polygon mesh, select Z Offset, On Polygon from the insert symbol menu.
Note: Z Offset settings Z-Base, Z-User 1, Z-User 2, and Z-Height are now toggles. So you can easily insert symbols at the current Z-Base without having to change the Z Offset value each time.

A new TIN(Triangulated Irregular Network) surface modeler provides a comprehensive array of three-dimensional site modeling tools. The TIN modeler can connect a random series of survey points (3D markers) with triangular polygons. Once the polygons are generated, you can calculate the surface area of TIN models, use the flip valley option to flip the valley between coincident polygon edges, or create roads, foundation cuts, etc. with the 3D Knife. The drop point option lets you place 3D markers on the surface of inclined polygons. You can create polyline contours from polygon site models.



To access the TIN surface modeler, go to 3D Entity, Polygons, TIN Surface.

You can place a three-dimensional marker on a polygon at an inclined point.

To drop a 3D marker on a polygon, go to 3D Entity, Polygon, Drop Point.

You can make a topological contour map based on a group of three-dimensional points or polygons.

To generate two-dimensional contours from a three-dimensional surface, go to 3D Entity, Polygons, Gen. Contour.

A ruled surface function allows you to mesh polygon surfaces between Polylines and Contours.

To access the ruled surface modeler, go to 3D Entity, Polygons, Ruled Surf.
For the best results, draw a polyline boundary and use Geometry, Offset to create two boundaries to mesh together.

A three-dimensional knife allows you to interact with TIN surfaces to create roads, sidewalks, and foundation cuts. You can use the knife to cut out, raise, or depress irregular areas and paths on the building site. Since DataCAD also calculates the volume of the affected area, you can estimate the amount of fill that must be removed (if you are digging for a foundation or a roadway) or added (if you are building up part of the site). To differentiate the cut area, you can specify a different color from the rest of the TIN model. Further, you can select distinct colors for each level and/or side of the cut area.



To access the 3D Knife, go to 3D Entity, Polygons, and select 3D Knife.
Note: You only have to select the polygons that will be effected by the path to cut.

You can easily create two-dimensional sections from three-dimensional models using the new sectioning tool. Advanced options allow for automatically hatching and updating sections. You can also create hidden line sections. Straight, offset, and curved section paths are supported.

To access the sectioning tool, go to 3D Edit and select Section.

Section Settings Dialog

All-new multi-view windows provide up to 10 tear-off, resizable windows you can use to store and display various views of your project.

DataCAD 11 adds support for DWF format so you can view and distribute your drawings via the Internet.

To export your drawing to DWF format, go to File, Export, DWF.

We've enhanced the interface for assigning materials to o2c objects so you can control the origin, angle, and scale of any bitmap texture. In addition, you are no longer limited to 32,768 polygons per material.

Drawing layers can now be included when you create a PDF file directly from DataCAD. Note: Requires Adobe Reader version 6 or later to view layers. However, PDF files created by DataCAD 11 can be read by Adobe Reader versions 4 and 5.

To create a PDF file with layers, select Save As from the print preview window and enable Drawing Layers.

A user-definable, context-sensitive toolbar automatically changes to present related icons based on the menu you choose. A configuration dialog allows you to easily set which toolbar is related to a particular menu selection.



To associate a toolbar with a DataCAD command, go to the View pull-down menu, select Toolbars..., then Context.

User-defined keyboard macro sequences can now include up to 1,024 commands and there is no limit to the number of characters you can use in the sequence. We've also added a special PAUSE character so you can tell the macro to wait until you do something such as click or type. Go to the Help pull-down menu and select What's New? for more information.

You can call a command line alias by name when you define a macro sequence so you can take advantage of existing aliases.

Classic Menu Window, Navigation Pad, Projection Pad, and Status Panel are available. To enable these classic-style elements, go to View, Toolbars. If you would also like to have the classic look of raised buttons, go to the Interface tab in Program Preferences and check Classic Buttons.

A new bitmap orphans manager allows you to redefine paths for bitmaps you've already inserted into your drawing.

A new option allows you to disable the display of nested external references at the time you insert an XREF. You can also toggle the display of nested external references on a per XREF basis via the Reference File Manager or the context-sensitive pop-up menu. The display of nested references can be disabled globally with the Display Nested XREFs option in the Nested XREFs section of the Misc. tab of Program Preferences.

Multiple XREFs of the same file now use a single memory space. Used in combination with the Display Nested XREFs toggle, you can significantly reduce the amount of memory required to open your drawings that contain XREFs.

Multiple self-referencing XREFs now use the same memory space so DataCAD no longer creates a new swap file every time you reference a drawing into itself.

A new option, Save with GoTo Views, has been added to the Current Plot Scale section of the Misc. tab of Program Preferences. This lets you save the current plot scale with a GoTo View when you create it.

You can now set the line overshoot value globally so that it applies to all entities equally. The global line overshoot is scale-independent and is defined as a real-world, plotted distance. You can access the Overshoots menu from the Line Type menu. Note: Overshoot must be toggled on in the Display menu in order to view/plot line overshoots.

The contour search routine has been updated to handle line/arc and arc/arc conditions that were not supported previously.

The two line trim command has been updated to handle line/arc and arc/arc conditions that were not supported previously.

Line Types (up to 255) are now stored in your drawing file. Now, you don't have to worry about providing custom line type definitions to your colleagues when you give them copies of your drawings. DataCAD 11.01.00 automatically converts your line type definitions from DCADWIN.LIN to individual .DLT files stored in \DataCAD\Support Files\Line Types.

Now, anything you draw can be converted into a new line type. The line type creator allows you to select entities in your drawing (up to 65,536) to define one segment of a custom line type. You can begin using your new line type immediately.

A line type manager has been added to the Line Type menu. Select Line Manage from the Line Type menu to access a dialog for loading or re-loading external line type definitions into your drawing. You can also set the End Correction and Default Spacing for embedded line type definitions.

Embedded hatch patterns have been optimized to require less memory. DataCAD 11.01.00 automatically converts your hatch pattern definitions from DCADWIN.PAT to individual .DHP files stored in \DataCAD\Support Files\Hatch Patterns.

A hatch pattern manager has been added to the Hatching menu. Select Manage from the Hatching menu to access a dialog for loading or re-loading external hatch pattern definitions into your drawing. You can also set the angle and scaling for embedded hatch pattern definitions.


Hatch Pattern Manager Dialog

Using the Screen Calibration dialog, accessible from the Interface Settings tab of Program Preferences, you can measure the test pattern in either decimal inches or millimeters in order to adjust both the screen scaling and aspect ratio.
