This Week's Software Tips

Congratulations July Winner
Congratulations to Tom Farley, who won the July drawing for a $100 gift card. Submit your tip (see guidelines below) for your favorite CAD software. If we publish your tip, we'll send you a Cadalyst T-shirt, and each month Cadalyst editors will randomly select one published tip and send a $100 gift card to its author.

New Code, New CAD Tips Site
"Hot Tip Harry's" code for August is here and ready to download. Check out Harry's August column to learn more about this month's batch. Head over to Cadalyst's new CAD Tips site to download your favorites. The August additions are listed under Recently Posted CAD Tips, or search for specific tips by tip number or keyword. Registered users also can review, post comments, and upload revised versions of code! Congratulations to John Walker, who created this month's top tip: Copy Attributes from Block to Block. These well-crafted VBA functions let you move attribute values from one block to another.

AutoCAD eTransmit and Registry Cleaners
Cadalyst Tip Patrol volunteer Billy Wooten thoughtfully shared this e-mail exchange by members of the South Plains (Texas) AutoCAD Users Group (SPAUG). The messages address problems associated with AutoCAD and popular registry cleaners such as Norton, McAfee, and others. According to SPAUG president Jeff Tippit, these programs can inadvertently remove key registry items that affect AutoCAD's eTransmit command.

Create Construction Layer
Arthur Gary Bissell sent this AutoCAD routine that creates a layer for construction only. "First it builds the layer and set its attributes. Use it, and when you are ready to get rid of it, simply type it out. If you need a clean drawing that has no junk on the screen, use this command to erase it. There is also a command to set it back to current. (The command can be reduced to simpler terms if the drafter wants. I personally like Snop.)"

(defun c:noplot ()
 (command "-layer" "make" "No_Plot" "c" "22" "" "plot" "no" "" "")
 (princ)
)
(defun c:setnoplot ()
 (command "-layer" "set" "no_plot" "")
 (princ)
)
(defun c:noplotrem ()
 (command "-layer" "set" "No_Plot" "freeze" "*" "" "erase" "all" "" "-layer" "thaw" "*" "set" "0" "" "-purge" "la" "no_plot" "y" "y")
 (princ)
)

NOTES FROM CADALYST TIP PATROL: You could create a script routine to accomplish this task as well. Be sure all the items on the construction layer are safe to delete. If you get careless and draw something you need on that layer — poof! Of course, the best thing to do is run the Layer Walk command to verify what's where before you snuff the construction layer. Using this command, we've found a few surprises that otherwise might have slipped past.

Revision Changes
Ronald Maneja sent in his method to determine the changes between two revisions of the same drawing:

  1. From one drawing, copy everything, then paste it into a new drawing as a block with the original coordinates. Then make it all one color -- for example, blue.

  2. From the other drawing, copy everything, then paste the block on the same coordinates in the new drawing, except make the newly pasted block a different color -- for example, red.

  3. You now have a new drawing with two blocks — red and blue — with each color being either the old or the new revision. Now you can inspect the drawings for any changes. If you put the red block on top of the blue one (draw order to front), you will see mostly the red. But if you spot any blue ones, it means that area has changes. Do this interchangeably to see what changed between the old and new drawing. You are not modifying the original of either drawing this way. You could have some blocks in the drawing that are not blue and red, which could be exploded for the purpose of inspecting the two colors.

NOTES FROM CADALYST TIP PATROL: Thank you for the helpful tip. Coordinating and documenting revisions isn't exactly a new problem; similar issues relate to old paper-and-mylar prints too. Alternatively, one could temporarily xref in one drawing and change all the new xref's layers to be one color, then proceed as described above.

Note: These follow-up tips have not been tested by the Cadalyst Tip Patrol.

Follow-Up: Easy Client-Specific AutoCAD Settings
Our August 4 tip about different AutoCAD settings for multiple clients inspired Dave Kimmey, Anthony Scala, Wayne Skrove, and Kenneth Dispoto to take it one step further by suggesting the creation of a desktop or Windows taskbar shortcut for each client. For example:

"C:\Program Files\AutoCAD 2008\acad.exe" /p "Client-ABC-2k8" /nologo

MicroStation Tip: Move Part of a Cell
Need to move part of a cell in MicroStation, but your CAD manager tells you not to drop any cells? Here's a way to do both.

Submit Your Tip

Submit Your Tip for your favorite CAD software. If we publish your tip, we'll send you a Cadalyst T-shirt, and each month Cadalyst editors will randomly select one published tip and send a $100 gift card to its author. Please remember:

  • Submit only code and other tips that are your original work (or provide the original source so we can include proper credit).
  • Tell us which software version you use.
By submitting code, 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.

Tips & Tools Weekly software tips for AutoCAD are reviewed by Cadalyst staff and the Tip Patrol before publication. Use all tips at your own discretion, please, and watch later editions of this newsletter for updates and corrections. We're sorry, but editors and Tip Patrol members cannot provide assistance with technical problems; please refer to Cadalyst's Hot Tip Harry-Help discussion forum.

Sincere thanks to our volunteer Tip Patrol members: Brian Benton, Don Boyer, Mitchell Hirschklau, R.K. McSwain, Kevin Sawyer, and Billy Wooten.
