This Week's Software Tips

Do you have a favorite tip or shortcut that you use every day in your CAD software? One that saves you time? Makes life easier? Share it with other readers and, if we publish it, we'll send you a “ Cadalyst: CAD the Way You Want It” t-shirt.

Follow-Up to Viewport Lock
James Hutchinson wrote to ask about the October 2 edition’s Viewport Lock tip. He says, “The routine works well on single layouts, but the Vpal and Vpau commands don’t fully work. They may change the color of the Vports in each layout tab, but they don’t change the status of the Vports. Has anyone else had this problem, or is it just me?” Checking back with the original submitter, Terry Holt, we found that he has the same problem, so he doesn’t use those commands. James, the good news is that you’re not alone. The bad news is that we don’t have a solution for you. Perhaps another Tips & Tools Weekly reader can come to the rescue?

Purging RegApps
Reader Andy Manninen offers this advice: "One tip that should be used more often in AutoCAD 2005 and later is purging RegApps when you receive a drawing from an outside source. RegApps in a file takes up hard drive space and bogs everything down."

  • Command: -PURGE
  • Enter type of unused objects to purge [Blocks/Dimstyles/LAyers/LTypes/Plotstyles/SHapes/textSTyles/
    Mlinestyles/Tablestyles/Regapps/All]: r
  • Enter name(s) to purge <*>: (Enter “*” for all.)
  • Verify each name to be purged? [Yes/No]: n

"This cleans out RegApps so they don’t add to your file size. I recently did this on a drawing from someone else and purged 156,000 registered applications, cutting the file size from 2.5 MB to 400 KB. The worst thing about RegApps is the virulent nature of them. If you xref an infected file into a clean drawing, the RegApps are brought into the new file. With behavior like that, you need to nip the problem in the bud or else you can corrupt a whole project in no time by opening a few drawings. Purging RegApps has known detrimental effects on the drawing or applications used."

NOTES FROM CADALYST TIP PATROL: Our Patrollers are in agreement that it’s necessary to purge RegApps on a regular basis, and this is a good solution. In addition, Manusoft offers a small utility program called SuperPurge ($30) that helps you rid your files of RegApps, as well as other things that a normal Purge command won’t, such as the Defpoints layer. You can also use it to hard purge items that are still in the drawing, so use it wisely.

Redir Command
Douglas Kochel’s office standard for attaching xrefs and images is to keep the path for these files relative without the full path statement. For whatever reason, this doesn't always happen. He often finds drawings with full paths on some of the references, and this can create problems later, such as a drive letter designation that changes during a server upgrade.

There are many ways to fix this, but Douglas has found the Redir command to be the best option to strip the path names off the references. The beauty of Redir is that if a path redirection doesn't find the file, the original remains as-is, he says.

For example, he keeps all image references (that are unique to a job) within a subfolder under the drawing folder named Images. If he sees full paths on the image references, he types Redir, presses Enter to bring up the Settings dialog box, selects Images, presses OK to continue and then types the asterisk symbol (*) to select all paths. The next prompt asks for the replacement folder, so he types IMAGES\.

All the images found in the Images folder are given relative paths. This works well with batch scripting too, he adds.

It’s very frustrating when you receive drawings from others and they don't contain relative paths for xrefs and images -- and this solution works well.

One Patroller notes, “The usefulness of this feature will, I think, have more to do with the structure of a given firm’s CAD filing protocols and standards. In some offices, the current revision drawing set is the one in the active folder. (Earlier revisions are saved in subfolders Rev-1, Rev-2, etc.). Storing the full path guarantees that if you need to see Rev-1 (even though the current revision is Rev-4) it won’t reference the wrong xref.”

Easy Toolbar Move
Frequent tipster Leonid Nemirovsky (visit his AutoLISP Web site) sends this quick tip he uses with AutoCAD 2006/2007:

After you lock toolbars and tool palettes in place, you can temporarily override that lock to move them by pressing and holding the CTRL key while moving the toolbars and tool palettes. Once they are in place, release the CTRL key and they are again locked.

This capability has been in the software for a while and is a handy tool. Of course, the wise user will have saved a workspace or two -- just in case.

MicroStation Tip -- Design Model Copied to a Sheet Metal
Question: I have a plot file all set up to plot from; however, I’m not using a sheet file. I would like to make a sheet view. Is there a way to copy the exact work I have done in my design file to a new sheet file? Or will I need to reference everything again, set up clip boundaries, levels, references and so forth?

Answer: Try saving a view in the design file. Next, switch to the sheet model and reference the current file. Now, select the view you saved in the design model and set Nesting to 1, then just data point on the screen to place the referenced view.

Axiom offers many MicroStation Tips on its Web site.
