Working with files

• Create startup suites, which allow you to specify the custom applications that start automatically when IntelliCAD starts.
• Export three-dimensional models to an .obj (Wavefront Technologies) file.
• Use the PDF Out command to export directly to a .pdf file. Previously you could export to .pdf files, but the new PDF Out command makes it easier to choose PDF as the output format.
• Import map files by connecting to PostgreSQL, MySQL, and WFS servers.
• Import polygons as closed polylines when using the Map Import command.
• For IntelliCAD versions that support working with BIM files:
  • Support for Autodesk® Revit® 2022 files.
  • In the BIM Properties pane, create and assign visibility states.
  • Attach .ifc, .rvt, and .rfa files using the Attach command.
  • Select, attach, and manage .ifc and .rvt underlays using the Explorer.
  • Use the Audit command to check for errors in .ifc files that are attached as underlays.
• For IntelliCAD versions that support editing and creation of .dgn files in their native format:
  • New commands: Audit, DXF Out, DWG Out, and Divide.
  • Work with associative dimensions and an initial implementation of associative hatches.
  • Import linetypes from .lin files.
  • Convert multiple .dgn file models to .dwg files when using IntelliCAD Converter.
  • Performance enhancements: (ssget) with an xData filter is more than 10x faster, sds_dictadd is 6x faster, regenerating and saving files with scalable linetypes is more than 10x faster, erasing entities is 4x faster, snapping is more than 10x faster, and redrawing, zooming, and panning are overall faster.
  • DGNGLOBALORIGIN system variable.

Viewing and vectorizing drawings

• Use section planes to visualize cross-sections of two- and three-dimensional entities and point clouds. The OpenGL ES graphics device is required.
• View models as though you are walking or flying through them.
• Use the view cube to check the current viewing direction and switch between preset views and custom viewing directions. The view cube displays in the upper right corner of the current viewport, or a different corner that you specify in view cube settings.
• Use the view and visual style controls in the upper left corner of the current viewport to quickly apply a different view and visual style to the model.

User interface

• Drag an entity from a drawing and drop it on a tool palette to add the corresponding entity-creation command to the tool palette.
• Specify the font used for text in the command bar.
• Use the new Visualize ribbon tab (for program versions that have a ribbon).

Selecting and modifying entities

• Use the 3D Positioner command to move and rotate entities interactively in three-dimensional space.
• Use the Reverse command to reverse the direction of lines, polylines, splines and helixes by swapping the first and last vertices of selected segments.
• Use the Break at Point command to break an entity into two without removing a portion of the entity.
• On the status bar, click Isolate/Unisolate Entities to temporarily hide selected entities or isolate selected entities so that all remaining entities are temporarily hidden. When you’re ready to view all entities again, use the Unisolate Entities command.
• Display selected entities with a glowing highlight effect. The OpenGL ES graphics device is required.
• Choose Hatch Selection and Group Selection in the user interface to toggle whether associated hatch entities are selected when selecting corresponding boundary entities, and whether associated group entities are selected when selecting sub-entities of groups.

Fields

• Regenerate field content automatically by using the Update Field command.
• Fields now include sheet set data.

Tables

Creating new drawings

The NEW command creates a new drawing using the New Drawing Wizard. Choose File > New from the menu bar, choose Application button > New in the ribbon (for IntelliCAD versions that have a ribbon), type NEW at the command prompt, or press Ctrl + N.

The QNEW command creates a new drawing automatically based on the default template. Click New on the Quick Access toolbar (for IntelliCAD versions that have a ribbon), click New on the Standard toolbar, or type QNEW at the command prompt. The default template is specified in Tools > Options > Paths/Files. The folder location is defined in the Templates folder item (top half of dialog box) and the template file is specified in Template file item (bottom half of dialog box). If a default template is not specified or cannot be found, the New Drawing Wizard displays.

The actions for the QNEW and NEW commands are also determined by the FILEDIA and STARTUP system variables.

ANNOAUTOSCALE system variable

The default value is now "-4".

CURSORMODE system variable

Determines whether the cursor color changes when the cursor moves over entities or areas that have the same color. By default, a logical XOR is used, so the color of the cursor is inverted if the cursor overlaps an area of the same color. In some cases, it can be useful to turn this system variable off to enhance visibility of the cursor, for example if underlying entities are gray.

Type: Integer

Saved: In the registry

Range: 0 (XOR turned off), 1 (XOR turned on)

Default: 1

ENHERRORHANDLING system variable

Determines whether enhanced error handling is turned on. By default this system variable is turned off, and IntelliCAD catches its own exceptions. But if you use custom DLLs with IntelliCAD, consider turning this system variable on and IntelliCAD will also catch exceptions from the DLL.

Type: Integer

Saved: In the registry

Range: 0 (Off), 1 (On)

Default: 0

SDS API Documentation

sds_dobjll*

struct sds_dobjll* sds_dispobjs(const sds_name nmEntity, int nDispMode);

Return a linked list of sds_dobjll object types.

Each sds_dobjll type describes a small linear geometric segment of the entity being decomposed. Each sds_dobjll contains information specific to each segment, such as type, color, number of points, and contains a chain of sds_real types that can be translated into points (either 2D or 3D) depending on its type.

For example, a red circle would return a number of line segments that are all red and with points that are 3D points. If you place the segments end to end, they would create an entity that looks similar to a true circle when in fact it is created from many short straight line segments. The more segments you have, the smoother the circle will be.

As another example, a rectangle would return a chain of 4 sds_dobjll objects, each having information on its type, color, and number of points (2). The chain of sds_real point data would contain a start point and end point of each segment in the rectangle.

The argument is the linked list returned by a prior call to sds_dispobjs().

sds_freedispobjs

void sds_freedispobjs(struct sds_dobjll *pDispObjs);

Free up memory allocated by a previous call to sds_dispobjs().

The argument is the same as the return value after sds_dispobjs() is called.

Running VSTA custom applications from IntelliCAD is similar to working with VBA custom applications. Use the following commands on the Tools > Visual Studio Tools for Applications menu for working with VSTA:

• VSTA Add-in Manager (vstaload) — Manages the Microsoft® Visual Studio Tools for Applications (VSTA) programs.
• VSTA IDE (vsta or alias vstaide) — Starts the Visual Studio Tools for Applications (VSTA) program and displays the VSTA window.
• Load .NET Application (netload) — Opens the Choose .NET Assembly dialog box where you can specify a .NET .dll to load.

You can also type -vstarun in the command bar to run a VSTA method after a VSTA program is loaded.

New System Variables

FILETYPEASSOC

Controls whether IntelliCAD checks at IntelliCAD start-up whether .dwg files are associated with IntelliCAD.

The value can be one of the following:

0 = Does not verify the file association of .dwg files at IntelliCAD start-up.

1 = Verifies the file association and displays the File Association Warning dialog box if .dwg files are not associated with IntelliCAD.

2 = Verifies the file association and automatically associates .dwg files with IntelliCAD if .dwg files are not associated with IntelliCAD.

Type:     Integer

Saved:     In the registry

Range:     0-2

Default:     1

REGENONZOOM

Controls whether REGEN is used while zooming.

When large drawings with large coordinates are displayed in OpenGL, complex entities like text and polylines display with a reduced number of vectors which can cause a rough appearance. When REGENONZOOM is on (set to 1), IntelliCAD performs a cleanup after ZOOM to improve the display quality of these entities, however, this can also cause some performance degradation. Turning REGENONZOOM off (set to 0) will improve ZOOM performance but reduce display quality for large drawings with large coordinates.

Type:     Integer

Saved:     In the registry

Range:     0 (REGEN is not used during ZOOM), 1 (REGEN is used during ZOOM)

Default:     1

Operating systems

IntelliCAD has passed initial tests while running on an early version of the Microsoft® Windows® Vista™ operating system. Because IntelliCAD is still in the preliminary stages of providing full support of the Vista operating system, the following conditions must be met: log in to Vista as Administrator and disable User Access Control (UAC). Preliminary testing revealed that IntelliCAD may run up to two times slower, and even slower when using the Aero interface. To improve performance, it is recommended that you disable the Aero interface. For more details about whether your computer is ready for Windows Vista, go to http://www.microsoft.com/windows/products/windowsvista/buyorupgrade/upgradeadvisor.mspx.

Working with DWG 2007 files

Hiding 3D geometry in layout viewports

Certain command names removed

The following command names are obsolete and have been removed from IntelliCAD: REDIT, RASTERIN, -RASTERIN, and RCLIP. Their corresponding command names are: IMAGE, IMAGEATTACH, -IMAGEATTACH, and IMAGECLIP.

IntelliCAD 6.2 was released on 4/27/2006.

Assign true colors and color book colors

You’ve always been able to add color to your drawings using index colors, but now you use two new color features:

• True colors — Defined using 24-bit color, there are more than 16 million true colors from which you can choose.
• Color books — Defined with a list of colors, color books help you organize collections of colors. For example, you can store a unique color scheme in a color book for a client and then use colors only from that color book for the client’s drawings.

Work with raster images using ADeko Raster

IntelliCAD Professional version includes new raster imaging software to help you work with images in your drawings. Working with raster images is similar to previous IntelliCAD versions, with easy-to-use features located on the Image menu in IntelliCAD.

Export to PDF and 3D DWF format

You can export drawings to two new formats:

• PDF — Portable Document Format files allow you to distribute your drawing to others for viewing with Adobe® Acrobat® Reader®, which is free software that users can download, and for viewing, reviewing, and editing with Adobe® Acrobat.
• 3D DWF — 3D Design Web Format files can be viewed in a Web browser if Autodesk® DWF Viewer is also installed on the computer. DWF Viewer is a free tool from Autodesk® that always supported viewing 2D DWF files, but now supports viewing DWF files in three dimensions.

Use entity snaps

When using the extension option with Intersection Snap and Apparent Intersection Snap, IntelliCAD draws dashed extension lines to help guide you as you use the extension snap option.

If you are working in the command bar, you can modify the active command by typing m2p or mtp to enable a one-time snap to the midpoint of two points that you specify.

Edit text in the command line

The command bar and Prompt History window include enhanced text editing, including cutting, copying, and pasting text; copying the last command line or the entire command history; and repeating a previously executed command.

Create wipeout entities

Wipeouts are unique entities that can help you hide areas of your drawing. They display with the current background color, so the details behind the wipeout do not display or print. However, if your version of IntelliCAD does not include raster image capability (that is, does not include an Image menu), wipeout entities display, but the details behind the wipeouts also display.

Create audio notes from existing *.wav files

In addition to recording audio notes in IntelliCAD and attaching them to entities, you can now create audio notes from existing *.wav files. Audio notes created from an existing *.wav file are saved in the drawing file and the separate *.wav file remains unchanged.

View thumbnails of drawings

When you open or save a drawing, drawing files can be displayed in a number of ways, including by filename with or without the additional details. Now you can also view thumbnail images of drawing files.

You can also view thumbnail images when you browse drawing files on your computer using programs that came with your operating system, such as Windows® File Explorer or My Computer.

Importing 3D DWF files not supported

While you can export a drawing to 3D DWF format, you cannot import 3D DWF files. If you attempt to import a 3D DWF file, the drawing in IntelliCAD will be blank. Importing 3D DWF files is unsupported at this time.

2D DWF files may produce errors

If you open or audit a 2D DWF file, you may receive error messages or the file may become unusable. The ability to work with 2D DWF files is still under development.

Wipeout entities print as filled polygons

Wipeout entities print as polygons filled with the same color as the current background color. In some cases this may cause unexpected print results, for example, if printing on colored paper.

IntelliCAD 6.1 was released on 9/5/2005.

Create rendered images

IntelliCAD uses new and enhanced rendering features to create higher-quality and more photo-realistic images of models.

Both IntelliCAD Standard and IntelliCAD Professional include the new rendering solution, while some versions provide additional rendering capabilities with a complete set of materials, backgrounds, lighting options, and render settings.

Format text

New formatting features are available when you enter text using Insert > Multiline Text. You can specify text color, first line indents, paragraph indents, right indents, and tabs.

Attach and record audio

IntelliCAD provides the unique ability to record audio notes, which are sound clips attached to entities and available for playback at any time. For example, audio notes in a factory floor plan can describe maintenance activities for specific areas of the factory and employees can play the audio notes to hear instructions.

Work with 3D solids

In addition to slicing and sectioning solids, you can now slice regions and bodies (typically sheets). This feature is available if your IntelliCAD version supports editing ACIS solids.

Use entity snaps

You can now snap to hatch patterns when using entity snaps:

• Snap to the middle points and end points of hatch pattern lines.
• Snap to the nearest point and perpendicular point on a hatch pattern line.
• Snap to any intersection point or apparent intersection point where the pattern line intersects with other entities that are supported by entity snaps.

Use new system variables

New system variables include: AUDIOICON, AUDIOICONCOLOR, and AUDIOICONSCALE.

Multiline text

• The text height for multiline text is saved correctly now when exiting the MTEXT command dialog box.
• The formatting for the MTEXT command (Bold, Italic, and Underline) now works correctly.

• You can now use both begin and end curly braces appropriately with the MTEXT command.

• MTEXT entities can now be used as a cutting edge with the TRIM command.

Entity snaps

• Extended intersection snap now works properly.
• IntelliCAD snaps are no longer stuck on a single location and they no longer require that the snap be reset.

Hatches

• When moving hatches, any associated boundaries move with the hatch.
• The ARRAY, ARRAY3D, MIRROR, and MIRROR3D commands now work with hatch entities.
• Hatch scale is saved correctly.
• Solid hatches utilize all spline knot boundaries correctly. This also fixed minor problems with the display of Kanji characters.
• If a hatch entity has the same name as a hatch pattern in the ICAD.PAT file but contains a different definition, that entity's hatch definition is no longer redefined on save.
• Hatch entities work better with the CHANGE and ENTPROP commands.
• Enhanced performance when working with dense hatch patterns, including patterns that are too dense to display.
• Dynamic dragging is approximately five times faster when dragging inserted blocks that contain hatch entities.

Linetypes

• User-defined complex linetype patterns are now saved and displayed properly.
• IntelliCAD now works properly when multiple linetypes are imported at the same time.

Print features

• User-defined print style tables are now saved in C:\Documents and Settings\user\My Documents\Print Styles per Microsoft® Windows® logo requirements.
• The Print Style file name dialog box now disallows invalid file names.
• Long file names are now visible in the Print Style Table Editor dialog box.
• The options on the Printing tab found in Tools > Options are now unavailable when no drawings are open.
• IntelliCAD now works properly when print style settings cannot be detected.

ACIS and 3D solids

ACIS primitives are created with the current color setting now (not always BYLAYER).

Match properties

The MATCHPROP command copies the polyline width if all segments of the source polyline are the same width.

Entity properties

• The ENTPROP command allows you to change the width of a polyline correctly.
• Relative paths now work properly for entity hyperlinks.

Display

• Zoom Extents calculates the view correctly when entities are extended outside of the current view.
• You can view changes made with DVIEW without an additional REGEN.
• OLE objects remain visible even when links are broken.

• Dynamic mouse wheel zoom centers the zoom properly on the cursor location when using multiple monitors.

• All nested MINSERT entities now display properly.

• VPLAYER freeze now works properly for entities in paper space.
• Constant, invisible attributes now display properly when ATTDISP is ON.
• IntelliCAD consistently displays lineweights in model space viewports.
• Previously, if IntelliCAD could not properly display a single entity within a block, it would not display any of the remaining entities within the block definition. Remaining block entities now display when a single block entity cannot properly be displayed (for example, if a HATCH entity was too dense to display).

Command bar

• The performance of command bar line scrolling has been greatly improved.
• The command bar no longer randomly displays duplicate entries.
• The command bar stores its size correctly if you vertically resize it.

API calls

• Entmod will now correctly create and display attribute entities.

• Extrude works properly on entities created with the RETANGLE command.

• SOLID entities now properly honor entity color when DXF files are imported into IntelliCAD.
• The Load/Unload status (DXF group code 280) of image definitions is now saved properly.
• Grip selected entities can now be unselected by using the shift key (shift-pick, shift-window, shift-crossing).
• IntelliCAD includes improved handling of the sortents table when it contains references to deleted entities.
• Exploded blocks with a negative scale factor in one axis no longer rotate ellipse entities incorrectly.

Infrequent crash due to operating system memory leaks

If you are using the Windows(R) XP operating system, creating very complex drawings during a single IntelliCAD session may cause IntelliCAD to crash. This is because Windows XP leaks a small amount of memory each time you use certain IntelliCAD commands. If you use many of these commands (for example, drawing about 2,000 lines) during a single IntelliCAD session, IntelliCAD can crash.

Most users do not experience problems caused by these memory leaks. However, if you do experience problems, consider installing the hotfix available from Microsoft. For more information, go to:

http://support.microsoft.com/default.aspx?scid=kb;en-us;Q319740

IntelliCAD 6.0 was released on 5/3/2005.

Utilize performance enhancements

Assign print style tables

The following printing features have greatly enhanced your flexibility and control over the printing process:

• Previously you could use the PenMap/Width mapping to associate colors with specific pen widths on your printer. New print style tables allow you to still specify color-based settings, but also allow you to specify pen widths, linetypes, and lineweight regardless of color.
• Print style tables (.ctb and .stb files) are stored in files; you can share the files across multiple drawing files or with other users.
• Print style tables affect numerous existing features, including: New Drawing and New Drawing Wizard; Properties and Entity Properties toolbar; Change; IntelliCAD Explorer (Layers); Drawing Settings > Entity Creation tab; Status bar; Options > Paths/Files tab; Options > Printing tab; and Print > Advanced tab.

There are also several new commands for print style tables: Print Style (printstyle), Print Styles Manager (stylesmanager), Convert Drawing Print Style Tables (convertpstyles), and Convert CTB Print Style Table (convertctb).

Manage external references

Attaching and working with external references is now easier with the new Xref Manager. You can view a detailed list of the referenced drawing, or you can view a hierarchical display that shows how drawings are nested and related to one another. Quickly attach, detach, reload, bind, open, and change the path for all external references in the current drawing.

The Xref Manager allows you to use the same external reference features as in previous versions of IntelliCAD, but in a more efficient manner.

Work with 3D solids

IntelliCAD Standard version now supports viewing and limited editing of 3D solids, including moving, rotating, and scaling. IntelliCAD Professional version still allows you to create and more completely edit 3D solids.

Use entity snaps

The existing Intersection Snap has a new Extended option, which snaps to the logical location where two entities would intersect if they were of infinite length.

The new Apparent Intersection Snap tool snaps to the intersection of two entities that are not in the same plane but seem to intersect in the current view. You can also use its Extended option, which snaps to the logical location where two entities would intersect if they were of infinite length.

Customize more options

The following features are new to the Tools > Options dialog box:

• General tab — Set the default save format. Specify how drawings are opened.
  Paths/Files tab Specify search paths for print style tables.
• Display tab — Use Up/Down arrows in the command history. Show or hide the Model and Layout tabs. Show or hide scroll bars.
  Profiles tab Create and manage drawing environment profiles.
• Printing tab — Specify headers and footers for all drawings. Assign default print style table settings for new drawings.

Save and restore drawing environment profiles

Customize the settings that control your drawing environment, and then save and restore those settings in a profile. For example, if you prefer working with custom menus and toolbars, you can save these settings as your own profile.

Profiles can be helpful if you have multiple users with different preferences, or if you are a single user who works on various projects that require unique settings. You can even export your profile and bring it with you when you work on a different computer.

Navigate model space and paper space

Use the enhanced Model/Paper Space control in the status bar to switch more efficiently between model space and paper space on either the Model tab or a Layout tab.

You can also change the display of the Model and Layout tabs in the following ways:

• Show or hide the Model and Layout tabs.
• Reorder the position of the Layout tabs.

Work in the command bar

In the command bar, you can do the following:

• Select text, and then right-click to copy, cut, and paste.
• Press Ctrl + K and Ctrl + L to move forward and backward in the command history.
• Use the Up and Down arrows to scroll the command history, if enabled by choosing Tools > Options.

Choose single IntelliCAD sessions

Use the new Single Session command (type singleton) to choose whether IntelliCAD can be started one time or multiple times simultaneously.

Use new system variables

New system variables include: APBOX, CPLOTSTYLE, CTRLMOUSE, DEFLPSTYLE, DEFPLSTYLE, DEFPLSTYLETBL, FONTALT, PSTYLEMODE, PSTYLEPOLICY, MBUTTONPAN, SAVEROUNDTRIP, and LAYOUTTAB.

IntelliCAD 5 was released on 10/24/2004.

Navigate with the Model and Layout tabs

New tabs located at the bottom of the drawing area allow you to switch how you view your drawing.

Use the new Model tab to create your drawing. When you are ready to print, you can optionally use one or more Layout tabs to design how you want your drawing to look when it prints on paper.

While working on a Layout tab, you can still view and work with your drawing on the Model tab, but you can also add items for printing, such as a title block or legend, that do not appear on the Model tab. When you are ready to view and work with only the model again, simply click the Model tab.

Apply lineweights

The width of entities in your drawing can be controlled with the new lineweight feature. You can assign lineweights to entities and layers, and you can also specify whether they display or print.

Work with files

There are many new file formats supported for opening, saving, and exporting files.

You can now open these additional files:

• Design Web Format™ (.dwf) files. DWF™ files allow you to distribute your drawing to others to view in a Web browser, review, and edit using free Autodesk® software and tools.
• AutoCAD 2004 drawing (.dwg) files.
• Drawing (.dwg) files that you suspect are damaged.
• Drawing template (.dwt) files.

In addition to recovering drawing files that you suspect are damaged, you can also audit files to check for errors.

You can also save to these additional file formats:

• AutoCAD 2004 drawing (.dwg) files.
• Drawing template (.dwt) files.

You can now export to these additional file formats:

• Design Web Format (.dwf) files.
• Scalable Vector Graphics (.svg) file format, which is a graphics file format and Web development language.
• In addition to the various new file formats that are supported, you can also drag-and-drop drawings from Web sites that support the Autodesk® i-drop® technology.

Reorder entities

When multiple entities overlap, you can change the order in which they display. Choose Tools > Draw Order to move entities to the front, back, or on top or below of another entity.

Use updated toolbars

You can now choose dimension styles from the Dimensioning toolbar.

When you modify the properties of entities in your drawing, you can use the new Entity Properties toolbar for your editing needs. Use the toolbar to access these features:

• Set layer by entity
• Set layers and access the IntelliCAD Explorer
• Select colors
• Select linetypes
• Select lineweights

Use keyboard and mouse shortcuts

You can use the following keyboard and mouse shortcuts:

• PAN: Ctrl + Shift + Hold down right mouse button.

• ZOOM IN AND OUT: Ctrl + Shift + Hold down left mouse button.

• ROTATE VIEW ABOUT Z-AXIS: Ctrl + Alt + Hold down right mouse button.

• ROTATE VIEW IN 3D ORBIT: Ctrl + Alt + Hold down left mouse button.
