Rhino to Alias
Rhino surface geometry is internally represented as B-rep objects. Rhino can export geometry in a wide variety of formats. In my experience the transfer of Rhino data to Alias is best done by using DWG format.

• Ensure that the modeling tolerance is set to the same as in Alias.
• In Rhino save as DWG format.
• Choose 2004 Natural format.
• Ensure that the output is set to Solids and Surfaces.
• Open the file in Alias.

The imported geometry is grouped under one node. The following are transferred.

• Construction settings.
• Layer names
• Layer color
• Model colors are transferred as shaders( The default color in Rhino is Black!)
• Surfaces
• Curves
• Joined surfaces as Shells.

Alias to Rhino
The best way to transfer is through IGES. Layer symmetry also get transferred as real surfaces.
