Technical notes

Operating systems

AcceliCAD has passed initial tests while running on an early version of the Microsoft® Windows® Vista™ operating system. Because AcceliCAD 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 AcceliCAD 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

The DWGCHECK feature in AutoCAD 2007 can cause a message to appear when a user opens AcceliCAD files in AutoCAD 2007. The message states that the file to be opened was created with an application other than AutoCAD.

Hiding 3D geometry in layout viewports

In some instances, 3D geometry is not hidden correctly when using the Hide command in layout viewports (the display may be distorted). Before using the Hide command, set the UCSs on the Model and Layout tabs to World so that the results of the Hide command are correct.

Overriding dimension arrowheads

Dimensions created in Autodesk® AutoCAD® 2007 that have dimension style overrides for arrowhead variables dimblk, dimblk1, dimblk2, or dimldrblk can lose the overrides if edited in AcceliCAD.

SDS Development

SDS DLLs built with earlier versions of AcceliCAD are not binary compatible with AcceliCAD 6.3. You will need to rebuild your SDS applications using the AcceliCAD 6.3 sds.lib and sds.h files.

Certain command names removed

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

What was new in AcceliCAD 6.2
New Features

Assign true colors and color book colors

You’ve always been able to add color to your drawings using index colors, but now you can 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.

Working with raster images is easier

AcceliCAD Professional and Pro Plus versions include new raster imaging software to help you work with images in your drawings. Working with raster images is similar to previous AcceliCAD versions, with easy-to-use features located on the Image menu in AcceliCAD.

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, AcceliCAD 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 AcceliCAD 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 AcceliCAD 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.

Use new and enhanced system variables

New system variables include: AUDIOICONCOLOR, NOMUTT, OSNAPCOORD, OSNAPHATCH, OSNAPZ, and RTSKIPCOUNT.

Enhanced system variables include: CECOLOR and SNAPCOLOR.

 

Important fixes

Display

  • In some cases AcceliCAD improperly clipped block sub-entities and they did not display.
  • The display of Chinese characters has improved due to better handling of double-byte characters.
  • The handling of visibility flags on attributes is improved.
  • Sub-entities in blocks properly support the display of lineweights.
  • Dimensions from earlier DWG versions are not translated to new locations when a drawing is opened.
  • Clipping is improved for overlapping viewports.
  • Mview viewports saved as "Off" in AcceliCAD do not display as "On" in Autodesk® AutoCAD®.
  • Draworder has been greatly improved for entities within blocks and external references.
  • Draworder is properly retained for edited entities (Copy, Block, Move, etc.).

Open and save files

  • AcceliCAD uses the new DWGdirect 1.14.02 libraries.
  • AcceliCAD properly saves binary extended entity data.
  • Extended entity data on group objects and view entities is saved properly.
  • Corrupted or missing plot styles do not prevent entities from being saved.
  • New actions are taken to help prevent data corruption when opening and saving drawings. If necessary, additional error messages display.
  • Opening files includes general performance improvements.
  • AcceliCAD saves the active drawing first (rather than non-active drawings first) when multiple files are open and AcceliCAD is closed.

COM API calls (AcceliCAD Professional versions)

AcceliCAD now uses the 6.4 VBA SDK version.

Print parameters can be set correctly through the COM API.

Technical notes

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 AcceliCAD 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.

 

Late-breaking documentation

LISPINIT system variable

Determines whether the LISP environment is re-initialized when a new drawing is created or opened. When set to 1, the LISP environment is re-initialized when opening or creating a new drawing. When set to 0, the LISP environment is saved and used in the new drawing.

Type: Integer

Saved: In the registry

Range: 0 (Off = Does not re-initialize LISP), 1 (On = Re-initializes LISP)

Default: 1

Attach Raster Image command

In addition to typing imageattach in the command bar to attach raster images to a drawing, you can also type rasterin.

 

What was new in AcceliCAD 6.1

New Features

Create rendered images

AcceliCAD uses new and enhanced rendering features to create higher-quality and more photo-realistic images of models.  Advanced rendering is now standard on all levels of AcceliCAD including Standard, Professional, and Pro Plus.

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

AcceliCAD 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 AcceliCAD 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.

Important Fixes

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.
  • AcceliCAD 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.
  • AcceliCAD 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.

  • Constant, invisible attributes now display properly when ATTDISP is ON.
  • AcceliCAD consistently displays lineweights in model space viewports.
  • Previously, if AcceliCAD 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.

  • Exploded blocks with a negative scale factor in one axis no longer rotate ellipse entities incorrectly.

 

Technical Notes

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 AcceliCAD session may cause AcceliCAD to crash. This is because Windows XP leaks a small amount of memory each time you use certain AcceliCAD commands. If you use many of these commands (for example, drawing about 2,000 lines) during a single AcceliCAD session, AcceliCAD 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

What was new in AcceliCAD 6.0

AcceliCAD 6.0 includes enhancements that boost the graphics performance between 400% and 1000%. With these enhancements AcceliCAD is now able to handle larger drawings than ever before.

Printing has been greatly enhanced by giving users more flexibility and control over the printing process. New print style tables allow users to still specify color-based settings, but also allow users to specify pen widths, linetypes, and lineweights regardless of color. The print style tables are stored in files (.ctb and .stb files), allowing users to apply them in other drawings and share them with other users.

Other enhancements are

  • Management of external references
  • Intersection Snap with a new Extended option,
  • Save and restore drawing environment files
  • Easier navigation between model space and paper space.

See below for a more detailed list of what’s new in AcceliCAD 6

Assigning print style tables

The following printing features have greatly enhanced 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; AcceliCAD 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).

Managing 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 AcceliCAD, but in a more efficient manner.

Working with 3D solids

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

Using 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 AcceliCAD sessions

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

Using new system variables

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

Performance enhancements

Many AcceliCAD features include increased performance. The following table describes the main enhancements and estimated performance increases.
