By playing the two-minute demo video, you can judge if XNurbs is the most powerful and easiest-to-use NURBS software ever developed. XNurbs delivers unprecedented power for designing NURBS surfaces:

  • Unlimited capacity for solving NURBS: Its optimization algorithm can solve virtually any NURBS surface on the fly (regardless of how complex the constraints are).
  • High-quality surfaces: Its optimization algorithm uses energy-minimization method to generate the smoothest NURBS surfaces that satisfy all the inputted constraints – this is why the surface quality generated by XNurbs is so good.
  • Easy-to-use: it uses one simple UI for all kinds of NURBS modeling.
  • Native CAD surfaces: XNurbs generates native CAD surfaces, i.e., trimmed NURBS surfaces, which can be directly used for any CAD modeling operations.


Example: Generating a surface from 12 curve constraints (with G2 Continuity along the boundary curves).
