Abstract
Sweep is useful in CAD modeling process. But its precision is hard to control when we use discrete modeling method. In this paper, the sweep surface is constructed by projected-based approach. Vector and distance methods are proposed to detect the local self-intersection of sweep surface. Beside these, it gives the precision control methods in the corner of sweep surface to improve the precision. Finally, we discuss the factors that influence the precision of sweep surface.
