Surface modeling

Create mathematically smooth surfaces using relatively few control vertices 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 parameterization and continuity. Convert NURBS and subdivision surfaces to polygon meshes, and vice versa. Use precise spline-based curve and surface construction tools.
