hi,
I am looking for a lisp routine that seperates layers out to individual drawings, i use lay2dwg which is fine but i want to either edit this (which i cant becuase it is VLX) or find one that automatically adds th "prefix" of the original file name as this is tedious when doing over 1000's of drawings. does anyone have any clues what to do (other than write another routine) thanks

Good idea with the prefix. Added now to the Lay2Dwg version 1.2 - see Download.
