I can't see how it would be very hurtfull for someone to hack this scaling into the PCB tool, but then again, I haven't actually read the source either. IMHO such a scaling should be there, since in reality you can't assume there is a CAM tool or that people have the sufficient Postscript knowledge. > I have to lern mor about Postcrip. <xscale> <yscale> scale In Postscript the parameters comes before the call.
