Hello All, I have a part "Butterfly" which I mirrored to create a Left & Right configs. So, in config Left, I simply suppress the mirror feature. Except, in the config Right I want to cut or cut with surf using a plane, but no joy. It seems that I can't consume the part, but SW complains that it can't create the cut because of geometric conditions!? It certainly should be a simple thing to create a L & R config in one part right?? BTW, up until now I've always just mirror the part and create a new part, but I've run into problems with that way of doing things so I thought I'd try this. Am I wrong in thinking one part with two configs is better than two parts? TIA, Muggs
