【Abstract】 A new geometric constraint solving method is presented. The reduction is carried out by using geometric constraint graph based on the point clusters. Then the sequence of reduction is computed and the geometric model is rebuilded. This algorithm is efficient, reliable and flexible. Based on this method, we develop the geometric constraint solver by using object oriented C++, which is a major component of BYLCAD system.更多还原
