| 摘 要： | 在回顾CAD系统的几类系统模型并分析其优缺点的基础上，立足于CAD系统的开放性、集成性和效率，运用基于组件的软件工程技术，提出了CAD系统组件模型，并详细地分析了模型中各组件的功能和组件间的通讯.系统模型具有两级总线结构，较之以往的模型，其开放性大大提高，便于实现结构灵活、开放性强的实用系统.同时，组件也为软件复用建立了良好的基础.

| Abstract: | Based on the research of previous models of CAD systems, the component-based model is presented in this paper, aiming at the openness, integration and efficiency of CAD systems. Functions of components and communication among them are discussed in detail. The model has a double-bus architecture, is better in openness than the previous models, is proved to be a solid base for the modelling and implementation of efficient CAD systems with clear architecture. In addition, components can be used as the base of software reuse. |
