Just because some devices have 3 pins for technical reasons? I think a symbol in a schematic should be abstract, and a capacitor is a two pin device from its physics. I started with special footprints with pin 3 renamed to 1, DJ suggests this too, so I go on using it. The only minor problem is, that I have to keep my footprints sorted, I have to care that I newer use such a modified footprint when I really need 3 pins, i.e. for a potentiometer. My current solution: Have general 3 pin devices, with a local (not public) copy with pin 3 renamed to 1. I was not able to find a nice name to this modified copy, so I append @2. This should remember me. Now I have true three pin devices named i.e. TRIM_TB_3N_1000D__Sprague-Goodman_Spec-1.fp and the special, local copy named trim_tb_3n_1000d__sprague-goodman_spe...@2.fp Best regards Stefan Salewski _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
