T-Splines for Rhino end of life

I’ll take this one: Which specific capabilities do you need? Advance sub-d for accurate design. Seek to develop sub-d workflow with tools to enable generation of forms with specific region parameter numerical definition. While such can be done presently with existing sub-d tools (convert, match, snap to surface, loft) value will be added by any advance to the simplicity, speed, and effectiveness at numerically defining and controlling specific localized regions of a larger sub-d, especially…

Might be prudent to give Clayoo a whirl…
