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?
