Are you really talking about "draw inverted polygons in the solder mask" or do you mean inverted polygons in the copper. The later would be indeed very nice, and I can remember talk about this on this list. But inverted polygons in the solder mask -- I have no idea for which we need this. We have this for pins and pads. Why would you want to remove solder resist from other areas of the pcb. For gang solder mask, to ensure that there is no solder resist between adjoining pads? _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
