Hi All!
I'm new to the world of AutoLISP and would appreciate some help. I'd like a lisp routine that deletes specific layers (and any entities within them) from all of the drawings in a particular directory (which I can select at the beginning of the routine). The list of layers can be specific to the routine since all of the drawings have the same ones. it more like something Batch freeze/thaw written by lee mac and i also attached the example of the lisp routine by lee mac that i mention before.
Thanks in advance for the help!
