Is it possible to import a multi patch trimmed nurb surface model and convert it to a usable Sub-D model in Rhino?
Hello - you’d have to go through the Mesh stage. For untrimmed surfaces,
SubDFromMesh (a test command, not finished) may be the thing. For trimmed faces, I think the only way is to
Mesh the object and
SubDFromMesh I’d say, depending on what you have, that this is unlikely to be what you’re after though.
