Great forum this, quick and good answers, been scratching my head with this
one as well.
I have a small project, about 10x10xm bottom layer, smaller rectangle on
the top layer.
Trick here is that there's supposed to be a hole near the middle, the top
layer is supposed to have copper to the edge of the hole so that's solved.
My problem is that on the bottom layer I need to have a copper free area of
1mm around the 2mm hole (1mm radius hole, 2mm radius free space)
I have tried bRestrict and bKeepout, didn't help, I guess these are perhaps
just to keep away components from that area?
I had some result using a polygon, but the copper around the hole was not
circular around the edge (not when viewing Gerber either) and polygons are
enormous in size, 1.5MB instead of 1kB file...
I've also thought about using "Holes" but there's no restriction you can
set to the layer. I basically just need to do the same as the bStop layer
but for the bottom layer instead.
