Shape control of swept surface with profiles
Shape control techniques for swept surface using profiles are developed in this paper. The characteristics of the swept surface are used to reduce the shape control of the swept surface to modify the contour shapes by using profiles. This method is more convenient and more intuitive for the user. The deformed region of the contour is defined by deformation rules proposed in this paper. The robustness and efficiency of this technique are verified by many examples implemented in the commercial geometric modeling software gems 5.0 developed by the CAD Center of Tsinghua University.
