T-Splines v.4.0 introduced new modeling features that were highly anticipated by the community. For example, it addressed the issue where star points on the edge of a model previously prevented a completely smooth appearance. With this version, it is now possible to add localized crease effects without compromising the overall smoothness of the model..

McNeel recognized the gap left by T-Splines and introduced native geometry in Rhino 7, which has been further refined in modern versions. Rhino SubD allows you to create highly precise, organic shapes that convert directly into manufacturable NURBS. It is stable, fully supported, and requires no external plugins. 2. Autodesk Fusion
