Yannada,

Thanks for the .3dm i/o plugin for MODO tip. The existence of this plugin further consolidates MoI and Modo as a powerful modeling combo.

The plugin however only imports and exports polygon meshes.

 

The ability to being directly able to convert between NURBS and SDS is something which much more interesting.

For Rhino users there are 2 different plugins available to convert polygon meshes into NURBS. First there is the T-Splines for Rhino plugin and there is also available something called Smurf or Smurf3D.
