Topic: Return to last layer

[42]

I have been following the last post with intrest and next to no lisp. You may be intrested in the following file that I have had for a while that I was able to add to enable new layer creation, collection of variables and returning to their original state once finished.

and to close

Code: [Select]

(setvar "OSMODE" OS)
(command ".LAYER" "S" CLYR "")
(setvar "ORTHOMODE" OM)

You will need the following drawing to use the previous post

looks interesting, I will give it a try first thing Monday morning

42,
if you are interested, here is a routine i found awhile back and altered it.
It does not require the block as the insulation is a pline.

I use the previous version of this file witout the error checking. What I have found is pline routine increases the file size more than the block. Both have their place, the pline cane be cut to size if required. I will certainally try it out. Thanks.
Well it seems to work, I will replace insul1 with it.
