Make that change to match your style and do it consistently to avoid debugging. Since I dislike having house keeping i/o cluttering up the symbol, what I've (mostly) converted to is breaking symbols into at least two pieces, one for power supply, and one (or more) for function. So if you copy a symbol with hidden nets, simply remove the nets. Then the new symbol will drop into place where ever the original was. Make another symbol for power supply, and assign it the same refdes when you place it. -dave ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Replace net= attributes with something else, for example power= attributes in each sybol with hidden power pins (keeping the same syntax for simplicity). Then a special tool can be created to add an external net= attribute or add/create the suitable power symbol.

Re: gEDA-user: gschem: How to overwrite invisible attributes?
Why not just remove the hidden nets from the symbols? With mulitple values of Vcc (or GND) the hidden nets create a lot of hidden problems. Indeed, for symbols created by myself I do not use net attributes for power supply. I prefer to use visible power pins or to divide larger symbols into one separate power symbol. But there are some existing gschem-symbols with these net-attributes... OK, maybe I should make a local copy and remove the hidden nets.
