I am new to full Autocad (2002) having used 2002LT previously with LTXpress Tools and LTExtender for lisp. (The combination worked but was very unstable, crashing ACLT several times a day.) With that setup, the GROUP and UNGROUP commands (buttons) worked very simply, easily grouping and ungrouping any objects selected. In full 2002 the GROUP cammond works fine, but UNGROUP yields "Unknown command". HELP says groups can be ungrouped but does not say how. The only way I have been able to ungroup items is using Explode, which explodes every object including polylines and hatches... not good. What am I missing? Do I need a lisp routine for it, and what would it be? Thanks, Joe
