3dsmax to tsSkin?

Hi guys, I have some mesh organic 3dsmax objects.

I would like to use rather Rhino, like 3dsmax but I have already done the model. What could I do?

I think Rhino (NURBS) is better for Architectural modelling. I tried to import my 3ds file to Rhino and scan it:

Curve- Project Curves- Rebuild Curve- tsSplitCurves- tsSkin

But I didnt get back my shape.
Could you help me?
Thank you!
