【Abstract】 This paper adopted hypergraph to represent constraint graph, and geometric reasoning was used to solve constraints, meanwhile, the computing of geometric entities was based on feature points. This method can realize parametric design with multi constraint driven (such as area constraint). It is proved to be efficient and has been used as a tool for parametric design in AutoCAD.更多还原
