Rhino has at least 20 imp/exp format. If we can get our model in & out cleanly between Rhino & Freeship you can turn Freeship into a great lofting program. Rhino can do the topside better. Maxsurf got the message:

"Maxsurf V12, which is in beta test at the moment, does import trimmed surfaces from Rhino. It should be shipped to users in the next few weeks. Note that the import is using native Rhino 3dm files.

From the Maxsurf V12 user manual -

Maxsurf - Rhinoceros bi-directional data exchange
Rhino .3dm files may now be imported and exported directly to/from Maxsurf.
Full NURBS surface geometry exchange is supported as well as information such as surface colours, names and trimming."
