We just recived a dwaring back from one of our contractors, and they have renamed all our layers by adding "0379-006" (the job #) to the start of all the names.. then added their own layers.. I need to find all the "changed" layers and remove the "0379-006".. I did a qick seach and found a few ideas.. but none specific to this situation... TIA. (btw, this lisp only needs to run in one drawing.. if that matters)
