This is pretty different from T-Splines. T-Splines in a sort of hybrid between Sub-Ds and NURBS. Also it’s mainly for modeling. This software is for scanned data or dense meshes that need to be converted to NURBS. So if i am creating the geometry in Rhino and am looking for a way to control/make smoother surfaces T-Spines is a great option. We use it at work and so far so good. Geomagic is not really a modeler.

T-splines is similar–lets you polymodel in Rhino while maintaining the ability to switch to NURBS.
