That's the problem with embedded nets. If your design has multiple Vcc's or your system has multiple grounds you will end up with lot of symbols. I use a separate power symbol for logic. There is a script at http://www.luciani.org/geda/util/util-index.html that will create power symbols and logic symbols without embedded nets. Give the power and logic symbol the same refdes. > Second on a 9 pin sub min D I have pins 10 and 11 showing up as shorts > since I have connected the mounting pin/studs to ground. Can I edit the > symbol on the schematic with net=Gnd:10 etc without hitting a snag? I would create a symbol that shows a pin 10 as connected to the shell. Change the footprint to have both shell pins numbered as 10.
