Hier findest du die neue Inventor FAQ

In den Autodesk Labs gibt es ein neues Add-In für Inventor 2010, das den Import von Rhino *.3dm Dateien erlaubt.

This technology preview gives you more flexibility when creating designs with vendor or customer data by allowing you to directly import Rhino files into Autodesk Inventor. This translator reads Rhino files(*.3dm) bringing solids, surfaces, wires, and points into Autodesk Inventor to be directly utilized while modeling. Being able to import directly from Rhino files eliminates the need to convert the Rhino data to make it usable in your projects.
