| Abstract: | The present paper covers a new parametric design model based on system realization, which forms the relationship of constraints' mapping according to the design process, maps the constraints to graphical unit so as to update the design with a more suitable way, and reduces the complexity of the constraint solver . The system could add the constraints that user defined and the system identified simultaneously, and offer the function of copy the sub graph. The practice proved that this model is simple and shows a quick interactive speed, it could catch on the design purpose more exactly. |
