Hi,

I'm busy with a product modeling job. I've used MoI to create the basic forms, and am finishing the model using ZBrush.

It would be very convenient for the manufacturer if I could deliver the final product model in ST(E)P format in stead of a polygon-based format.

What's the best way of converting a (medium to high) polygon model to a solid? In the past I've used T-Splines for Rhino for this purpose, but I haven't got that anymore.

T-Splines has merged with Fusion 360, can I maybe use that for efficient poly to solid conversion? And is Fusion 360 still free, or would I have to go for an expensive Autodesk subscription?

Are Max Smirnov's polygon import and subdivision plug-in commands maybe suitable for this, or do they only work properly when importing and subdividing low-poly quad models?

It'd be great if the converted solid isn't a huge mess of tiny stitched NURBS surfaces.

Many thanks in advance for your help.
