Negative layers would be awesome. Having the mask as an actual negative layer would also be great, and allow some custom things to be done on with the mask (e.g. exposing copper strips along the edge for chassis/shielding connections) _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
