gEDA-user: Adding inner polygons to a plane

   Sometimes, I want to add an inner polygon area to a plane in PCB. The
   area might be a power supply which only has to cover a small area; e.g.
   1.8V in a predominantly 3.3V area. However, if I just draw a polygon on
   top of the plane, there is no cut-out formed and I get shorts. To do
   what I want, I must cut a hole in the main polygon plane, then add my
   smaller polygon into it. This is very time consuming and changing the
   plane once created is very difficult. Is there a way to get PCB to
   support nested polygons?
