The issue is that, if you're etching through 5 mil of brass, you

Given that I'm doing this at home, I'm limited in what I can apply to
it. Otherwise I'd just buy a 1mil CNC laser and cut them out, or have
someone else make them ;-)

It doesn't seem to be possible to have polygon clearance around an unplated
via (a via with the hole flag). As soon as the hole flag is enabled, any
clearance between the edge of the hole and the polygon it is sitting in
disappears. As a result, it's not possible to add mounting holes in a

So this was a bug that's been fixed in the CVS version?

No, but the polygon code was completely rewritten since then. The new
version seems to do the right thing.

I have a related question: I can't seem to add polygon clearance to text
either. Is this intentional? I want to add some (copper) text to an area
covered by a polygon.
