I can see how that wouldn't be desirable.

Correct me if I'm wrong (please!) But inlining only replaces the
type 1 line with the (transformed) lines from the subfile it
referenced. Right? It doesn't mean figuring out if 2 polygons could
be joined into 1 polygon, does it?
If this is so, then inlining of primitives seems to also be
undesirable.
I mean why have primitives at all if they aren't refenced after
the inlining is done? And if you are planning on inling the
primitives in this ring case, then you may as well just write up
the ring yourself with fewer polygons seeing as how you aren't
planning on taking advantage of the primitive files in the end
anyway. Right?
Thanks for showing me the other view points though, I'm still
learning alot of this stuff.
