Abstract: This article discusses the method and process to extract effective information and component form legacy CAD system. Combined with the new development domain of CAD, it proposes a new CAD system model based on software bus architecture and analyses the functions of each component composed the model. With better openess and integrity, the system enables designers at different places to work collaboratively. An example the architecture used in the DrCAD system is presented.

Key words: CAD, software bus, architecture

摘要: 探讨从遗留的CAD系统中获得有效信息、组件的方法和过程,结合当前CAD领域的新发展,提出一种新的基于软件总线体系结构的CAD系统模型,并分析了组成该模型的各组件的功能特性。该系统具有较好的开放性与集成性,使处于异地的设计人员能协同工作。文中也给出了该体系结构在博士CAD系统中的应用实例。
