| Abstract: | The 3D geometric constraint has important significance to assembly modeling, assembly process planning and concurrent engineering. According to the parameters in multibody system, the general constraint relation can be represented with antithesis and spinor. A directed graph representation of geometry constraints system is given. A general geometry constraint engine (CBA) is developed with O O method. |
