Surface modelling

Create mathematically smooth surfaces using relatively few control vertexes via NURBS or hierarchical subdivision surfaces. Add complexity to different regions of subdivision surfaces. Attach, detach, align, stitch together, extend, fillet or rebuild NURBS surfaces with a high degree of control over parameterisation and continuity. Convert NURBS and subdivision surfaces to polygon meshes, and vice versa. Use precise spline-based curve and surface construction tools.
