T-Splines 2.0 for Rhino is now available for purchase & download.  In this version they’ve added several new tools for free-form surfaces, and for the first time a full-suite of polygonal modeling tools.

For the first time ever, a full suite of box modeling tools are available fully integrated within Rhino and fully compatible with NURBS surfacing. Designers can now directly create and edit surfaces faster and quicker than ever before, with full confidence that the end result will be a smooth, gap-free manufacturable model.”

A free trial is available for download, or it can be purchased for $549 ($99 to upgrade).
