ACTCAD Software Updates & Fixes

The IntelliCAD Technology Consortium (ITC) today announced the release of IntelliCAD 8.2.

IntelliCAD 8.2 is a major release that includes new support for exporting 3D .pdf files; more options added to existing features that export 2D .pdf files, export .bmp files, and attach underlays; new in-place multiline text editor; new support for maximizing and minimizing viewports; and various other new commands such as BCOUNT, IMAGEFRAMEMODE, FIELD, and TEXTTOFRONT. IntelliCAD 8.2 also includes improved performance when working with complex blocks, panning and zooming, exporting to .pdf files, and more.

IntelliCAD 8.2 is optionally available with the ability to open, save, create, and edit .dgn files in the native DGN format. IntelliCAD 8.2 also includes optional integration with Artisan Renderer to create photorealistic images of models quickly using a wide range of pre-set materials and lighting setups combined with the ability to create custom lights and realistic materials.

For IntelliCAD versions that include a ribbon, IntelliCAD 8.2 now includes ribbon panel expanders, ribbon versioning support, and the ability to customize the ribbon using the CUSTOMIZE command.

IntelliCAD 8.2 is supported on Microsoft® Windows® 10, Windows 8, Windows 7, and Windows Vista®, including 32-bit and 64-bit versions.

The IntelliCAD Technology Consortium (ITC) today announced the release of IntelliCAD 8.0.

Available in both 64-bit and 32-bit versions, IntelliCAD 8.0 opens, saves, and creates .dwg files, including the latest 2014 file format. New features include layer states, layer filters with search, layer transparency and viewport freeze, .cui custom menu files, quick select, 3D orbit, additional grid capabilities, Collada (.dae) file import, MrSID MG4 compressed raster image support, and more.

Working with groups in IntelliCAD Explorer

In IntelliCAD Explorer, you can manage groups that exist in the open drawing, create new groups, manage the entities contained in a group, and change the settings of groups.

To display groups in IntelliCAD Explorer

Do one of the following:

• Choose Settings > Explore Groups.
• On the Settings toolbar, click the Explore Groups tool.
• Type expgroups and then press Enter.

To create a new group using IntelliCAD Explorer

1. In Explorer, do one of the following:
   • Choose Edit > New > Group.
   • Click the New Item tool.

   A new group is added as Anonymous.

2. Type the name for the new group by typing over the highlighted default text, and then press Enter.
3. Click the [+] tool to select the entities to be included in the group; click the [-] tool to select the entities to remove from the group.
   You can also click the Number of Entities column and choose Add Entities or Remove Entities.
4. Press Enter when done selecting entities.
5. To complete the command, close the window.

To modify a group using IntelliCAD Explorer

1. In Explorer, select Groups.
2. To rename a group, do one of the following:
   • Select the group, choose Edit > Rename, type a new name, and then press Enter.
   • Click the group name you want to change, type a new name, and then press Enter.
   • Right-click the group name you want to change, and from the shortcut menu, select Rename, type a new name, and then press Enter.
3. To add entities to a group, select the group and click the [+] tool, select the entities in the drawing to be included in the group, then press Enter when done selecting entities.
4. To remove entities from a group, select the group and click the [-] tool, select the entities in the drawing to remove from the group, then press Enter when done selecting entities.
5. To make a group selectable or unselectable in the drawing, click Selectable for it.
6. To reorder the entities in a group, select the group and click the Reorder tool, make you selections, then click OK. Click [?] for more details about the options in the Reorder Grouped Entities dialog box.
7. To select a group in the drawing and have that group highlighted in the list of groups, click the Highlight tool, select the desired group, then press Enter. The appropriate group will be highlighted in the list.
8. To complete the command, close the window.

Using VSTA

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

New Features:

Multiline text

• Multiline text options menu supports stacked text, overline text, number/list settings, background settings, and more.

• Layouts can be copied between drawings in IntelliCAD Explorer.
