T-splines - V.4.0.r11183 Download !new! Jun 2026

If you are starting a new project or want to avoid the risks of legacy software, consider these modern alternatives:

Conclusion T‑Splines represent a powerful middle ground between the rigid regularity of tensor‑product splines and the flexibility of subdivision approaches. A release labeled v4.0.r11183 likely reflects a mature implementation with incremental improvements; when downloading any specific release, verify source authenticity, license terms, and compatibility with your toolchain. For designers and engineers focused on high‑quality freeform surfaces and efficient local refinement, T‑Splines remain a compelling technology bridging CAD modeling and numerical simulation.

Officially known as , it was released on January 19, 2015. This version marked a significant shift as it only supports 64-bit versions of Rhino 5 , ending compatibility with Rhino 5 (32-bit) and all previous versions of Rhino entirely.

Understanding T-Splines v4.0 for Rhino: Features, Legacy, and Modern Alternatives

T-Splines is a revolutionary 3D modeling technology that bridges the gap between NURBS (Non-Uniform Rational B-Splines) and subdivision surface modeling. Developed by T-Splines, Inc.—later acquired by Autodesk in 2011—T-Splines introduced a new paradigm for creating smooth, freeform surfaces that combine the precision of NURBS with the flexibility of polygonal modeling.
