This Week's Software Tips
Send us your tip, code or shortcut for your favorite CAD software. If we publish it, we'll send you a "Cadalyst: CAD the Way You Want It" T-shirt, and each month Cadalyst editors will randomly select one published tip and send $100 to its author. Please submit only code and other tips that are your original work, or provide the original source so we can include proper credit. By submitting code to Cadalyst, you grant Cadalyst the right to print and distribute your code in print, digitally and by other means. Cadalyst and individual authors retain all rights to the code; published code is not to be used for commercial purposes.
Congratulations November Winner!
Follow-Up to Extreme Trim
Follow-Up to Dimensions
"Generally, it's my view that it's a dangerous and lazy practice to dimension in paper space:
It works only with 2D, flat drawings or right-angle viewed 3D objects, such as Plan, Elevation and Top. Dimensions are wrong when the object is viewed from a different angle. Draw a cube and dimension it in paper space (DIMASSOC = 2). When the cube is in plan view, you see a square and it works fine. Now use SE ISO View and the dimensions became shorter. This could be dangerous if a drawing is edited and the views are changed. The manufactured product could be much smaller than intended.
"A 2D drawing dimensioned in paper space when DIMASSOC is not set to 2 is potentially a total disaster when the drawing is complex with a lot of dimensions. If there is major change to drawing scale, you can spend days repositioning objects.
Follow-Up to Textmask Tidbit
One of our Tip Patrollers who was on the scene to review the original tip noticed that pdf995 (a free PDF maker) performs in much the same manner as Wipeout, but you then must zoom in to the point where the wipeouts/textmask becomes opaque so it's impossible to read the text, he says.
A second Patroller points out information that you can find in AutoCAD's Help menu (AutoCAD Express Tools / Help / Index Tab / Textmask). Among other things, the Help suggests having your vendors download the free Autodesk DWF Viewer, and sending them DWF files instead of PDFs.
Change Layer Color
NOTES FROM CADALYST TIP PATROL: Our Patrollers agree that the tip works. One offers some suggested additions to the code:
With those additions in mind, here's an augmented version of the AutoLISP function:
NOTES FROM CADALYST TIP PATROL: Our Tip Patroller who is familiar with these commands has used the Revolve command only with 3D objects and says he wouldn't use the Revolve command with 2D objects. What Kellie is doing is possible using the Rotate command and then modifying the UCS. This Patroller says he would use the UCS command and rotate it about the x-, y- or z-axis (using the right-hand rule to determine positive and negative rotation). If necessary, you can also specify a new origin point.
AutoCAD Plot Macro
"Also, change to your particular paper size and plot style. I have several of these macros on a toolbar, one for every printer and paper size that I frequently use. You can type in '-plot' at the Command line and follow the prompts to see what everything in the macro is for. You may want to change a few of them around to further customize the macro."
^C^C_-PLOT;Y;MODEL;PLOTTER;custom 1: 36 x 22 in. (landscape);I;L;N;L;1=$M=$(getvar,dimscale);C;Y;PLOTTER.ctb;Y;A;N;N;Y;
NOTES FROM CADALYST TIP PATROL: Our Patrollers didn't test this specific macro because of its many variables. For example, you get different prompts if you're plotting a layout as opposed to plotting from model space. The important point here is that you can drive the Plot command from the Command line in a script or menu macro. Just walk through the -Plot command once by hand at the Command line, writing down the answers to the prompts. Then follow the example posted above, test, fix and repeat for your own plotting macro.
Toggle Layer Plot Status
NOTES FROM CADALYST TIP PATROL: Our intrepid Patrollers agree that this code works well and is handy enough to be an Express Tool. Our LISP expert points out one small potential hang-up: The layer name Defpoints will only be trapped in this routine if it contains all uppercase or all lowercase letters. It's possible for someone to rename this layer to something such as Defpoints or DeFpOiNtS, in which case the no-plot toggle is set to Plot -- but still doesn't plot. That Patroller volunteered this new version of the code, which performs the same function but is more condensed:

MicroStation Tip – Where Did That Cell Come From?
Answer: You can use the Identify or Place Cell command, then the Message Center will show the cell library of origin. This may not be the most efficient way, but it beats looking through cell libraries to find it.
Axiom offers many MicroStation Tips on its MicroStationTips.com Web site.
