| Abstract: | To describe the solving system of plane geometry constraints, the concept of float DOF is applied in graph theory to represent the state of the constraints system. And through the establishment of the variable passing n~les, changes of the parameters can make rational flow in the graph so that the system can give a clarity expression and achieve the effect of fast driven of the graphics system changes. |
