Freeform Surface Modelling

  • Freeform surface modelling is the art of engineering Freeform Surfaces with a CAD or CAID system.
  • Freeform surface, or freeform surfacing, is used in CAD and other computer graphics software to describe the skin of a 3D geometric element.
  • Freeform surfaces do not have rigid radial dimensions, unlike regular surfaces. They are used to describe forms such as turbine blades, car bodies and boat hulls.
  • Initially developed for the automotive and aerospace industries, freeform surfacing is now widely used in all engineering design disciplines from consumer goods products to ships.
  • Most systems today use nonuniform rational B-spline (NURBS) mathematics to describe the surface forms; however, there are other methods such as Gorden surfaces or Coon surfaces.
  • Free Surface Modelling
    • G0 ? position (touching)
    • G1 ? tangent (angle)
    • G2 ? curvature (radius)
    • G3 ? acceleration (rate of change of curvature)
    • To achieve a high quality NURBS or Bezier surface, degrees of 5 or greater are generally used
