We're talking about issues of parasitic capacitance here? I wasn't worrying about those issues. A SMT part would connect to two different nets and thus the two pads would be isolated. The way I envision it there would be a line cut halfway between the two pads (width somewhat out of our control because it is due to the depth of cut and the V-profile bit). > > If you want to save something like that directly from > > PCB, though, the polygon code could do all of your Inkscape steps > > internally. > > Ahhh.... so... does that mean the polygon code could be easily tweaked to > produce the vector outlines of all the pads on the paste layer?

It can do what you describe (in fact, it does, it just probably doesn't output in the format you want). But it can also do the things you did in Inkscape (union areas, etc) -- Ben Jackson AD7GD <b...@ben.com> http://www.ben.com/ _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
