As is now connections are stored as lines and an attribute could be added to one of the lines, I guess it would be possible to achieve this with current file format although there may be a need split lines in two sometimes to form segments. > > What would be needed in gschem would a function to select all line segments belonging to a net and a function selecting all lines belonging to a segment which possibly also sometimes have to split a line in the middle to form a segment. Then an attribute is added or changed it will be attached to only one off the lines and then I guess it will work with gnetlist. Igor2 and I have been fixated on the idea of placing additional attributes on parts of nets so that you can have things like trace width passed to PCB. I am looking at having gnetlist understand when someone wants a star ground by looking at how nets are angled when they meet. There is the question of how much of gnetlist should be moved into libgeda since I don't want to do this in scheme. -- Home http://evanfoss.googlepages.com/ Work http://forge.abcd.harvard.edu/gf/project/epl_engineering/wiki/
