I would never use this type of connector and only connect one ground pin.

When I build parts with multiple pins all of which I want connected I give them different numbers. There may be other types of examples where this is needed but I've never hit one. thoughts from Joe T. >so if the net specified connect to pin 2 it would make a electrical >connection to any of the pins and be done > >if you specified that it was pin 2.1 it would connect to that sub pin. > >if you specified 2.* it would require connection on all sub pins. > >this would provide for the most options in how to handle internally >connected pins with the same numbering. > > >thoughts gang? > >Steve > > >_______________________________________________ >geda-user mailing list >geda-user@moria.seul.org >http://www.seul.org/cgi-bin/mailman/listinfo/geda-user > > > _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
