| Abstract: | This paper reports a method of finding the solution on the basis of geometric constraint. On the basis of comprehension of engineering drawings, the method can recognize dimensional constrains and geometric topologic constrains automatically and build up a geometric constrain model and a geometric constraint graph which take nodes as the core,and then geometically reason it by reduction algorithms to bring about parametric design. These method can solve it with high efficiency. |
