What's new in AcceliCAD 2008 V2

New features

Work with the newest DWG 2007 format AcceliCAD 2008 V2 supports the updated DWG 2007 format, including 2008 object support, by opening, printing, and saving new entity types, such as annotations, and recognizing new system variables.

    New and enhanced system variables

    Changed system variables include: ACADVER and DIMSCALE.

    New system variables supported for DWG file compatibility: ANNOALLVISIBLE, ANNOTATIVEDWG, CANNOSCALE, CANNOSCALEVALUE, CMLEADERSTYLE, DGNFRAME, DXEVAL, DIMANNO, LAYEREVAL, LAYERNOTIFY, LIGHTINUNITS, LIGHTSINBLOCKS, LINEARBRIGHTNESS, LINEARCONTRAST, LOGEXPBRIGHTNESS, LOGEXPCONTRAST, LOGEXPDAYLIGHT, LOGEXPMIDTONES, LOGEXPPHYSICALSCALE, MSLTSCALE, RENDERUSERLIGHTS, SAVEFIDELITY, and VPLAYEROVERRIDES.

     

    Important fixes

    Open and save files

    • Corrupted drawings containing more than one Layer 0 are now recovered correctly.

    Raster images (AcceliCAD 2008 V2 Professional versions)

    • The Image Quality command now displays the current value.

    Hatches

    • Aborting a hatch boundary selection could cause AcceliCAD to crash.

    • Some hatch patterns could change scale on save; this has been fixed.

    What was new in AcceliCAD 2008

    New features

    Work with DWG 2007 files

    AcceliCAD supports opening, modifying, printing, and saving drawings in DWG 2007 format. The DWG 2007 format is now the default format in which AcceliCAD drawings are saved.

    Create and edit color books

    Now you can create and edit color books, which help you organize collections of colors, right from AcceliCAD.

    Work with images

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

    Use new layout viewport features

    There are several new features for layout viewports:

    • Snap to model space entities from paper space.
    • Lock layout viewports to lock the model space view or location while panning or zooming in paper space.
    • Assign a unique UCS to a layout viewport.

    Manage character sets for drawings

    AcceliCAD allows you to manage which character set is assigned to a drawing. This unique feature can be very helpful when sharing or distributing drawings in geographic regions where several languages are used that require different character sets to display text properly.

    Reverse the zoom direction of the mouse wheel

    Instead of zooming in and out by moving the mouse wheel forward and backward, you can reverse the settings to zoom in when spinning the mouse wheel backward and zoom out when spinning the wheel forward. This can be especially helpful if you use the mouse with your left hand.

    Use new and enhanced system variables

    New system variables include: 3DDWFPREC, DIMARCSYM, DWGCODEPAGE, IMAGEHLT, RASTERVERNUM, RTDISPLAY, UCSVP, and ZOOMWHEELL.

    Enhanced system variables include: DELOBJ, FACETRATIO, HALOGAP, HIDEPRECISION, OBSCUREDCOLOR, OBSCUREDLTYPE, OLEQUALITY, and TEXTEVAL.

    New system variables supported for DWG file compatibility: CAMERADISPLAY, CAMERAHEIGHT, CMATERIAL, CSHADOW, DEFAULTLIGHTING, DEFAULTLIGHTINGTYPE, DIMFXL, DIMFXLON, DIMJOGANGLE, DIMLTEX1, DIMLTEX2, DIMLTYPE, DIMTFILL, DIMTFILLCLR, DRAGVS, DWFFRAME, DWFOSNAP, DWGCHECK, GRIDDISPLAY, GRIDMAJOR, INTERFERECOLOR, INTERFEREOBJVS, LATITUDE, LEGACYCTRLPICK, LIGHTGLYPHDISPLAY, LIGHTLISTSTATE, LOFTANG1, LOFTANG2, LOFTMAG1, LOFTMAG2, LOFTNORMALS, LOFTPARAM, LOGNITUDE, NORTHDIRECTION, OSOPTIONS, PERSPECTIVE, PSOLHEIGHT, PSOLWIDTH, PUBLISHALLSHEETS, SHADOWPLANELOCATION, SHOWHIST, SOLIDHIST, STEPSIZE, STEPSPERSEC, SUNSTATUS, TIMEZONE, UCSDETECT, VSBACKGROUNDS, VSEDGEJITTER, VSEDGEOVERHANG, VSEDGES, VSEDGESMOOTH, VSFACECOLORMODE, VSFACEHIGHLIGHT, VSFACEOPACITY, VSFACESTYLE, VSHALOGAP, VSHIDEPRECISION, VSINTERSECTIONCOLOR, VSINTERSECTIONEDGES, VSINTERSECTIONLTYPE, VSISOONTOP, VSLIGHTINQUALITY, VSMATERIALMODE, VSMONOCOLOR, VSOBSCUREDCOLOR, VSOBSCUREDEDGES, VSOBSCUREDLTYPE, VSSHADOWS, VSSILHEDGES, and VSSILHWIDTH.

    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.

    The objects, methods, and properties in the following table have been updated or added to the COM application program interface.

    • DCL list boxes handle truncation correctly.

    Hatches

    • When associative hatches are erased, their boundaries are no longer erased with them.
    • Direction on ellipses and elliptical arcs are not changed when the drawing is saved, which had previously caused issues when these entities were used as hatch boundaries.
    • The Bhatch command can use entities inside a block as a boundary edge.
    • User-defined hatch patterns do not have their base point reset when the drawing is saved.
    • Non-associative hatches do not display as associative in the Hatch dialog box.

    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

    Entity snaps

    Hatches

    Linetypes

    Print features

    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

    Display

    Command bar

    API calls

    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.
