Best import format from Non-Rhino to NURBS/Rhino

Hi there,

I use Rhino exclusively for CAD but sometimes work with others that have different software like 3DS Max, Maya, Blender or Lightwave. Is there a good or better format that they can use to export files that I can import as NURBS or more easily convert to NURBS?

Thank you

In my experience, STEP or Iges are good format… but don’t know if all this softwares can export in this way…
For example, I think that 3DS Max can export only meshes… but I don’t use it so I could be wrong…

I usually use .3ds or .dwg and they work properly both ways :slight_smile:
