What’s New (V6.2)
V6.2 is powered by xn kernel 2025.0, which includes a number of enhancements. Except for surfacing quality improvements, the following are some of other main improvements:
1. For four sided surfaces or untrimmed NURBS surfaces, users can add internal constraints, e.g., points and curves.

2. For Quad-sided surfaces, XNurbs supports “L” sided, two sided, three sided and four sided surfaces.
