It's just a rectangular symbol with a vertical bar dividing it onto two boxes, a small one on the left and a larger one. The refdes goes in the small one, and the larger box is just for annotation. So, for example: for a board with 4 mounting screws, I have a stack of 4 of these with refdes H1..H4, and the comment says "#6 mounting hole" or some such in each one. The net effect is that it looks like a 2x4 spreadsheet in the corner of some page.
My current symbol is "heavy" :) in that it ties pin 1 of whatever the footprint is to ground. This is probably a bad idea, and I should have a pin on it -- every once in a while I want an isolated mounting hole. In an case, it keeps the net lister happy and gets the screw holes into the ground net and so forth. -dave _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
