Re: gEDA-user: Clearance in fiducials & blocking solder paste

   The problem with this approach is exactly what started off my quest for
   the Arc.  Namely the autorouter is routing through the keepout space on
   the fiducials.

   Arcs aren't allowed in footprints. You can overlay rectangular pads
   along an arc if you need to.
   The footprint I use for fiducials is below. The request from the
   assembly house was 1mm pad with 3mm clearance. The board that
   assembled my last board did not mention any problems (and the
   board worked ;)
