There is a GUI option. For GTK, it's in file->preferences, in the lesstif version it's edit->board sizes.
Clearance should depend on your board fab's design rules. For 8 mil spacing for example, you need 8 mil gap as well (it's spacing after all), so set your clearance accordingly. _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
