Groups are your physical layers on the board. You should order them from top to bottom (or bottom to top, I suppose) and mark the top/bottom special layers. Drawing layers are what the autorouter uses. You should hide any layer you don't want the autorouter to use, leaving the shown ones for it. Then optimize your rats and start the autorouter. _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
