Ok - read your bug report properly this time - and got answers to most of my questions. The following remain though.. what are the arcs and lines left on the component layer for? Just to show the outline? How have you constructed a polygon which has a hole in it (Or is it not meant to have a big hole?) PCB does not support defining a single ground-plane polygon with a hole in it. It can subtract holes out of one, but it does not support you defining its shape as anything other than a hole-less outline. If you have basically created a "C" shape, where the two ends of the C touch infintesimally, that "ought" to work, but if becomes very easy for numerical errors to get parts of the polygon self-intersecting. Could you elaborate how the polygon was constructed - obviously its too complex to have drawn by hand. I can imagine either a computer program, or using arcs + lines to clear away copper, then using the "MorphPolygons" action. As you might imagine though, scanning lists of coordinates in the PCB file isn't particularly easy to do - and I don't have any debugging tools to help show the order in which a polygon contour is created. _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
