T-splines are a type of spline that allows for more flexibility and control over the surface of a model compared to traditional splines or NURBS (Non-Uniform Rational B-Splines).

This new tool added a powerful and intuitive way to build geometry. It simplified the process of creating complex, swept forms, making the modeling workflow faster and more efficient.
