Build the Sweep Surface Transition define Transition strategy Approx define Approximation Strategy.

  • GeomFill_Section : The composed Function Location X Section is directly approximated.
  • GeomFill_Location : The location law is approximated, and the SweepSurface builds an algebraic composition of approximated location law and section law This option is Ok, if Section.Surface() methode is effective. Continuity : The continuity in v waiting on the surface Degmax : The maximum degree in v required on the surface Segmax : The maximum number of span in v required on the surface.
