Is there a working way to get NURBS curves into and out of Blender?
FBX supports this, but when I import an FBX with NURBS, the curve is not created. I've tried with several versions. FBXes exported with blender do not contain correct curve data.
OBJ export appears to work, but when I re-import them, the curve paramaterisation does not match what was exported.
IGES support doesn't appear to be available in the list of plugins, either.
