You can assemble frequently needed subcircuits in a special symbol and add them with one click to your sheet. Make sure to choose "include_component_as_individual_objects!" in the select component dialog. This will expose the symbols in the subcircuit-symbol. Otherwise you won't be able to edit their attributes. There are a few such convenience blocks in my section of gedasymbols.org (look for the "block" section). One of them deals with voltage regulators: http://www.gedasymbols.org/user/kai_martin_knaak/symbols/block/XLR-78xx-79xx.sym > as I am now for the Underwater Robotics Competition. The one in Space and Naval Warfare Systems Center? I watched some of the races on youtube. Seems like the task is getting harder over the years. ---<)kaimartin(>--- -- Kai-Martin Knaak Öffentlicher PGP-Schlüssel: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x6C0B9F53 ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

I had not seen or heard of that one before, and it would go great on the separate power and bypass cap page to link a specific capacitor with a specific IC.

I believe you are confusing pcb footprints with gschem symbols. They are very different things. Yes, my bad. i was writing quickly and imprecisely. It was exactly the SYMBOL that I was talking about, not the footprint. > Is there some > way to indicate which symbols are powerless and which have non-printing > power connections built in? From command line: grep net= `locate name-of-symbol.sym` From gschem: 1. Select the symbol. 2. Hierarchy>Down Symbol 3. Edit>Show/Hide Inv Text 4.

The .sch file is text, so a global change of of the symbol name does the trick. > I don't gattrib allows changing the actuacl symbol file used, > just a few of the attributes. These problems are why I recommend making project-specific copies of symbols rather than using the library symbols as-is. John Doty Noqsi Aerospace, Ltd. I had also done some gedit work on the file, and created an error I could not find to undo, so I stopped using direct editing on the .sch files. Perhaps on the next project, when I am not as far behind a hard schedule as I am now for the Underwater Robotics Competition.
