Re: gEDA-user: Outputting negative plane layers from pcb?

["harry eaton" <bumpelo@comcast.net>]

I just fabbed a board with them that had a complex ground plane and it came
back fine without a peep from them. I'm not sure why they demand negative
planes, probably because it's slightly easier to combine other designs onto
the same panel that way.

In any event it shouldn't be a problem.
