| Abstract: | In this paper, an object oriented parametric design model and its implementation are introduced. The geometric elements in the design model, such as line, arc, etc, are extracted as an abstract geometric object with common attributes and operations and are represented in a hierarchy according to the inheritance mechanism in the object oriented method. As a result, the model is semantic, highly flexible, fully expandable and exceptionally operational. Both forward and reverse searching and reasoning methods are used to obtain final solution of the parametric design model. This approach has been successfully applied to 2D and 2.5D geometric design problems, in which multiple solutions are found with implicit geometric constraints. A parametric design system based on the design model has been developed through C in PC environment. |
