Is this really related to gerber output? PCB program already has arbitrary shaped copper polygons. Your mentioned AND, OR, XOR operations will again generate copper polygons -- so it should be possible to handle negative stuff inside pcb program, without concerning gerbers. _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
