I don't think this new one has that kind of conversion in it, it seems that you can load polygon objects, but they are a kind of separate object type that can't interact directly with NURBS objects.

So they're more for things like importing a visual reference or something like that and not for actually converting into NURBS geometry.

See this thread on their forum that talks about this:

I've heard that Maya does have some kind of function in it for converting sub-d surfaces to NURBS, but it seems that right now the main one that people use for that kind of a thing is the T-splines Rhino plug-in. Also if you use 3DS Max, check out the new nPower converter: http://www.npowersoftware.com/subdtonurbsoverview.htm


I still think it would be cool if the T-splines guys made a simple standalone converter program that could be used for this kind of a conversion without having to buy the entire Rhino + full plug-in combination. Try asking them about that, I've suggested it to them before and maybe if they get enough requests they will cook it up.

Also if you have SolidWorks the T-splines guys have a new plug-in for that as well.
