With (command ".insert" (strcat "stamp-save=r:\cadd\proto\stamp-saveR16")...) I could insert any block and rename it while inserting, which would also redefine if it already existed. I want "r:\cadd\proto\stamp-saveR16" to come in as and redefine "stamp-save". How do I do the same here... (vlax-invoke-method LAYOUTNAME 'insertblock (vlax-3d-point '(0.0 0.0 0.0)) (strcat "stamp-saveR16=r:\cadd\proto\stamp-save") 1.0 1.0 1.0 0.0) The above causes an error. Using a qualified path\file alone works, but doesn't perform the rename on the fly. Can this be done with a simple tweak to this invoke-methode? Thanks, Mark
