Visose,

Thanks for the tips... also regarding the preview shortcut.  Very
nice.

I've got it working fabulously for surfaces now.  My next challenge is
to get it working with BReps as well.  Some of my "surfaces" are
actually polysurfaces, and I'd rather not have to set my collection of
curves separately for each surface that makes up the BRep.   Why is it
that the BRep analysis component doesn't provide uv coordinates???

As a workaround, I started developing a patch that explodes the BRep
and then analyzes the distance of the sample point to each component
surface, then selects the correct surface uv point for orientation
purposes.  My problem now is that it works great for one curve, but as
soon as I load the whole collection it freaks out and is only able to
select one surface for the whole collection.  Obviously this is no
better than exploding a BRep and feeding it through my original patch
(also not working).   I would like it to analyze each point
individually as if in a discrete loop, but I think I'm having a
problem of list lengths and redundant values, or in the structure of
the patch itself.  Any chance you can take a look and give me some
leads on how to pursue the logic of this one?
