Abstract

This paper puts forward a method of reconstruction of freeform surface in AutoCAD. According to the scanning beam 3D- data, by reverse count of control vertex points, making use of Add3Dmesh method to create bicubic B- spline surface, this paper realizes automatic reconstruction of freeform surface, improves the efficiency of modeling and design.
