illustration below shows a procedural surface on the left, and a NURBS surface
on the right.
Choose a Surface Creation Method
Create procedural and NURBS surfaces using the following methods:
Create surfaces from profiles (page 361). Create surfaces from profile
shapes composed of lines and curves with EXTRUDE, LOFT, PLANESURF,
REVOLVE, SURFNETWORK, and SWEEP.
Create surfaces from other surfaces (page 398). Blend, patch, extend,
fillet, and offset surfaces to create new surfaces (SURFBLEND, SURFPATCH,
SURFEXTEND, SURFFILLET and SURFOFFSET).
Convert objects into procedural surfaces (page 402). Convert existing
solids (including composite objects), surfaces, and meshes into procedural
surfaces (CONVTOSURFACE command).
Convert procedural surfaces into NURBS surfaces (page 403). Some
objects cannot be converted directly to NURBS (for example, mesh objects).
In that case, convert the object to a procedural surface and then convert
it to a NURBS surface. (CONVTONURBS command).
