What is a NURBS surface? Do I need to create NURBS surfaces for my application?
A NURBS (Non Uniform Rational B-Spline) surface is a mathematical model used for generating and representing the surface of a model. This model is continuous, as opposed to the discrete polygon model composed of triangles and vertices. NURBS surfaces are the standard method for importing and exporting data to CAD, CAM, and CAE applications, with ‘IGES’ and ‘STEP’ being two of the most common file interchange formats. Some applications can also accept polygon models, often using the ‘STL’ format. In most cases, the need for using NURBS or polygon models will be decided by the downstream requirements and applications. Geomagic Studio can produce either representation.
