Thanks for the idea. I just tried it, files with real R apertures for square pads and with G36-G37 blocks defining square pads. Gerbv exports G36 polygons when they are input as G36 polygons. Gerbv will export R apertures when they are input as R apertures. Viewer programs have no way of knowing that a defined polygon is a pad. It just knows it is a polygon. Now if some of these other programs worked as good as gerbv. I found a couple programs where a gerber trace will isolate through the polygon instead of becoming part of it.
