[I was thinking you'd reduce the mesh before trying to do the toolpaths. If that's what you did, I'd say the test was conclusive, but negative.]
I have made some progress though. I'm finding that it's not the number of triangles that causes the problems. It's how tight they fit in a given area. This is defined as the "resolution". I should have known that! For example, 1 million polys in a 2 cm x 2 cm area has issues, but 1 million polys in a 20 inch x 20 inch area works okay.
[That seems odd to me; I'd look for another explanation. After all, the program can use mm or inches, and has no internal check to see which is being used for a given operation, so 20 inches would be the same as 20 mm as far as it's concerned. Have you looked at your Rhino tolerances? Maybe they're set too high.]
So, I think I'm on the right track.
Thanks for the help.
