Glad to see the discussion prompt some delurking. Awesome. :) > The NURBSForTHREE library looks interesting, but it doesn't appear to have > any support for trim curves yet.

That is a pretty big limitation as nearly all CAD NURBS geometries have trimming curves. Someone could work on implementing reparameterization of trimmed NURBS to untrimmed NURBS (and this would be a useful feature to have), but there is some complex math and data structure work involved. That was part of my original plan for robust tessellation of NURBS, but Keith found a better way. Cheers!
