Topic: Really would prefer *CAB to get this section not to crash.. [Got.It!]

Excuse my ongoing illiteracy but if this wouldn't crash, it would really help. Any suggestions accepted. Thanks.

What version of what software are you using?

Do any errors display on the screen?

By crash do you mean you had to restart AutoCAD?

As it's worked for others you're going to have to give more information than that.

[mhupp]

This allows you to use snaps to pick points. enable nearest if you don't want to pick vertices of a polyline. Draw order (top) will affect what gets picked.

Got-it  https://www.theswamp.org/Smileys/black/idea.gif the copybase was causing the crash..
Sure glad this works - try it.
