Parameterized CAD System Based on Object-oriented Technology

Abstract

Abstract: Object-oriented method in the development of parameterized CAD system is discussed in this paper. According to the requirements of parametericzed CAD system, a new data structure based on polymorphism is introduced, which describes explicitly geometric constraints and enhances the reliability, stability and flexibility of the system. A tire bladder CAD system based on objected-oriented method has been used in industrial engineering.

摘要： 介绍了面向对象方法学在开发参数化CAD系统过程中的应用，并根据参数化CAD系统的需要提出了一种基于对象多态性的面向功能/数据的数据结构，该结构实现了几何约束的显式表示，增强了系统的可靠性、稳定性和灵活性。在此基础上开发的轮胎胶囊CAD系统已经用于工程实践，并取得良好效果。
