Enhanced Beta Presentation Software at Autodesk Labs
Autodesk unveiled the latest preview of Autodesk Impression software that gives architects and other CAD users a helping hand with creating illustrative presentation graphics from DWG and DWF files. The technology preview, available as a free download from Autodesk Labs, reportedly improves productivity, and ultimately client satisfaction, by virtually eliminating the manual labor previously required to develop compelling images from CAD drawings. To improve the product, the company sought customer input via interviews, comments e-mailed directly to Autodesk Labs, discussion forum exchanges and other feedback mechanisms.

Multi-CAD Benchmark Report Now Available
For a limited time, users can download a free copy of a new report by the Aberdeen Group titled "Multi-CAD Design Chain Benchmark Report: Insulating Engineering from Today's Multi-CAD Environment." Among the report's recommendations is the use of CAD translation software to reduce the problems and hidden costs associated with CAD data exchange between multiple applications. The research reportedly suggests that significant manufacturing problems and costs can be traced to poor or nonexistent CAD file compatibility between engineering applications. The report was partially sponsored by TransMagic, a developer of 3D CAD software products for translating 3D CAD data. The free offer ends February 23, 2007.

Start Up Switches
Frequent Tipster Brian Benton suggests using switches to start up AutoCAD 2007. He asks, "Do you have two or more ways that you need AutoCAD to start during the day? You can use Start Up Switches (or Icon Switches). When you click your desktop icon to start AutoCAD, you can program it to do more than just start the program. You can have it start with a specific user profile, run a script file, start sheet set manager, keep sheet set manager from starting, turn off the AutoCAD logo and more."

"To begin, right-click on your AutoCAD Icon, select Properties and go to the Shortcut tab. At the end of the Target line add this list of switches, making sure to leave a space between the end of the existing target in quotes and the new switch. For example, "C|Program Files\AutoCAD 2007\acad.exe" /nologo. You can also include multiple switches in your icon, just keep them separated with a space."

"drawing file name.dwg"

This opens a specified file every time you start CAD (this is great if you have a template file).

/b "script file name.scr"

This starts AutoCAD and runs a script file (make sure to include the full file path).

/layout "drawing file name.dwg"|"layout name"

This opens a file to a specified Layout Tab (make sure to separate the filename and layout name with the vertical bar).


Starts an ObjectARX or ObjectDBX file with AutoCAD.


Disables the hardware acceleration (this started with 2007).


Disables the splash screen. (You know you are starting AutoCAD, do you need a reminder about what you just did?)


Prevents the Sheet Set Manager from loading at start up.

/set "sheet set file name.dst"

Loads a particular Sheet Set File (you can create multiple icons for frequently used Sheet Sets).

/p "profile file name.arg"

Loads AutoCAD with a specific profile (my favorite switch).

/pl "publisher file name list.dsd"

Starts Publisher and processes the drawing files in the list.


Resets the default system pointing devise and creates a backup of the Acad****.cfg file.

/s "folder"

The folder specified is now designated as an additional support path (I suggest that you set this up in your options).

/t "template file name.dwt"

Creates a new drawing with your specified template file.  (This is a great tool to make sure users start with the template file for new drawings.)

"drawing file name.dwg" /v viewname

Opens a drawing to a certain set view.

/w "workspace name"

Opens a specific work space in AutoCAD 2007 (this one is very useful).

NOTES FROM CADALYST TIP PATROL: Both Patrollers who reviewed this tip agree it is very useful, especially if you are a CAD manager. One Patroller was able to modify the AutoCAD 2007 shortcut tab from the Properties window, but in 2005/2006 versions the shortcut tab was not available and he was not able modify the target textbox. He shares, "The closest I came to making any modifications in the past, with older versions of AutoCAD, was to copy the AutoCAD desktop icon and then follow the same procedure of right-clicking the icon and selecting properties. Then from the Properties window I modified the text from the 'Start in:' text box to look in a specific folder."

The second Patroller reminds users that some of these switches may apply only to certain releases. For example, the /w switch does not work in 2006 even though 2006 has workspaces, and the Sheet Set Manager switches would not apply to releases prior to 2005.

Drawings TABS for AutoCAD
Andrew McDonald suggests other users try this free and very useful software to manipulate multiple windows in AutoCAD. Link to for iDwgTab, a freeware utility program produced by BizIcom. The company states that iDwgTab runs on AutoCAD R2000 or above and some versions of AutoCAD LT.

NOTES FROM CADALYST TIP PATROL: While one of our Patrollers had difficulty with this program, the other found that it works as advertised on AutoCAD 2006/2007. For more Drawing Tabs programs, check out the list from Cadalyst Tip Patroller R.K. McSwain.

Continue Arcs
Jim Dee shares a short AutoLISP routine, ARC_CONTINUE.LSP, for continuing tangentially from either end of any arc. AutoCAD only allows continuing from the last point of the last arc drawn. To start the program, type Act at the Command prompt. When selecting an arc to continue, the program detects which endpoint of the arc you selected closest to and continues from that endpoint. The layer of the selected arc is also set to current so that the new arc is placed on the same layer.

NOTES FROM CADALYST TIP PATROL: Everyone agrees! This is a useful and well-commented tip!

Spell Check
Amanda Sowell finds AutoCAD's Spell command to be especially helpful when using text and checking for errors. Type Spell (or SP) at the Command line to bring up a spell-check dialog box after you click on the text you want to check. This is very useful for words commonly used in construction, but not in everyday vocabulary.

NOTES FROM CADALYST TIP PATROL: Your faithful Patrollers agree, "Yep, the Spell command has its benefits. A reminder: If there is a word not included in the dictionary and you know it's a proper word, click on the Add button and the word is appended to your custom dictionary."

Follow-Up: Solid Solprof
We had a couple of responses from readers on January 22's tip concerning the Solprof command:

Jim Dee says, "The one unfortunate thing about the Solprof command is that it doesn't work on viewports that are in perspective view. The solution I use to flatten viewports in perspective view is to plot to a DXB (data exchange binary) file. To do this you need to install the AutoCAD DXB File plot driver and then plot to a file using this driver. This creates a DXB file that you can then import into AutoCAD using the Dxbin command. This technique is great if you want to add trees and people to your perspective drawings in AutoCAD. There are a few limitations with the DXB driver, per the AutoCAD Help file. The driver produces 16-bit integer DXB files containing only vectors, DXB output is monochrome; all vectors are color 7, raster images and embedded OLE objects are not supported and the driver ignores object and plot style lineweights. "

Dick Figueras points out that "AutoCAD 2006 also has the Flatten command that works somewhat in the same way. When you use the Flatten command, the original model is no longer there, it's simply flattened (z is set to 0 for all entities). After using it, I then recommend using the 'overkill' command, which removes redundant lines and arcs and results in small 2D models."

Follow-Up: Framed Text
Instead of the tip found in the January 22 edition, Mark Northcott uses an Express Tool, Tcircle, to frame text. He says, "If you have Express tools, at the Command line, type in Tcircle and it offers you the chance to border any text with a circle, slot or rectangle. It can make multiple text boxes at the same time, plus lets you make the boxes a uniform size by length or width, or both. This tool has a lot of good functionality but it does have some cons, such as it taking a long time to complete (in my opinion) and it isn't associative to the bounding boxes of the text."

MicroStation Tip: DGNLIB Color Numbers in V8
Question: When attaching a DGNLIB in MicroStation V8, the color numbers are changed when the RGB values of the color number in the DGNLIB are different than the RGB values of the DGN. How can I prevent this?

Answer: There's a user preference in Workspace/Preferences/Reference called Remap Colors on Copy. Turn it off and you should be good to go.

Axiom offers many MicroStation Tips on its Web site.
