I was going to say also you could put a trace on a pcb layer with the no-drc attribute set so pcb doesn't complain, but I think that no-drc only works for the pcb 'DRC' feature which is really only about spacing and copper width, not about open/short connections which is handled by 'o' optimize rats. To me, they are both DRC issues but should probably be two separate flag. Regards, Colin
