If you want to separate the two grounds on schematic level too, they have to bear different net names. PCB will complain if you try to connect them with a track. There is official no way to make PCB accept two net names connected to the same polygon or track. However, there is a hack: Test for connectivity ignores text. So you can use a hyphen, or the letter I to bridge the two otherwise isolated grounds with copper. > 3.

This will cycle the thermal through a number of styles. All of them are four spokes, though. > 4. What is the current status of swapping in gEDA?

To swap gates, change the slot attribute in the schematic and forward the change to the layout.

To do it right, calls for change of formats and/or gschem receiving information from PCB. This means rather intrusive changes. It seems like the itch has not been strong enough for any of the developers to tackle the task. ---<)kaimartin(>--- -- Kai-Martin Knaak Email: k...@familieknaak.de http://pool.sks-keyservers.net:11371/pks/lookup?search=0x6C0B9F53 not happy with moderation of geda-user _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
