I'm glad you cleared that up as I thought tsplines allowed you to model with nurbs using sub'd techniques. To me this would be the single most leap forward for nurbs over the very limiting traditional nurbs tools, such as loft, sweep and network which tend to warp, twist & buckle nurbs surfaces even when used on minor changes of shape or direction.

I hope they do make a standalone product for tsplines that writes 3dm. That way it could be used with MoI.
