The Pads ASCII format uses a base unit of 0.00000002624671916 inches which is 1.0333354 nM
Converting it to metric causes an error of about 0.5 nM The PCB base unit is 0.00001 inches Converting it to metric causes an error of 19.7 nM All I can figure out about why pads uses that weird number is that multiplying it by 38100 converts the base unit to mills Multiplying it by 9678 converts the base to 10 microns with an error of .6 nM So making the base smaller will reduce error (no surprise) the question is what is a tolerable error? _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
