| Abstract: | With the background of bridge scheme design, this paper introduces the application of object-oriented method in the CAD system development. On the basis of the hierarchical topological feature of bridge structure and its components, the general object model representing bridge structure is established. Furthermore, the encapsulating method of its geometrical and topological information and method of linking the object model with graphics supported system are presented.The implementation of this model is also emphasized. |
