What is the recommended file format to export curves and surfaces from Rhino, into Alias and back to Rhino while retaining the layer structure?
I expected to be able to do this in DWG, however, the Rhino docs show that this format apparently doesn’t support NURBS (even though Autocad does)…
When I export .step files, the objects created in the default layer are nested in new default layers per object.
Also, how do I match these import settings? The “User Defined” settings are saved by Rhino.
