Amen to that.

I've just been compiling an open source Linux package, GTS, that seems
to have a fairly robust set of mesh boolean operations. I got it from I haven't tried anything very difficult yet, and I
don't know how its algorithms stack up to those of Magics and whatnot,
but it's one more tool -- and you can't beat the price.
