Create a new layer based on another layer's name

charles_neelyFG4LK — Mon, 24 Mar 2025 12:59:48 GMT

I want to be able to select objects and have new layers created based on the layers of the selection set. The name would be the layers in the selection set with a prefix of “CD”. Any guidance on how to accomplish this?

That is great! Gets me what I'm looking for except its adding a suffix and I want to add a prefix to the layer name.

So just modify the code so you would add your prefix sections of the code that looks like this:

(strcat (cdr (assoc 8

to this:

(strcat "CD-" (cdr (assoc 8

Then remove the suffix from sections of the code that looks like this:

(entget forVar))) " - FUTURE")

to this:

(entget forVar))) )
