This is probably the wrong group for this but I was wondering if anyone has had this before. I have a program that creates a "wblock" via Lisp. The problem is that I'm using Acad 2004 and have my settings to save as Acad 2000. Other users are still using Acad 2002 and are able to open any drawings that were saved from this program but the "wblock" drawings are not able to be opened. Is there a diferent setting for the version when "wblock" is used? Thanks, Bill
