摘　　要：协同设计是 CAD/CAM网络化研究的重要方面 ,对协同设计技术的研究是多方面的 ,本文侧重研究了支持机械零件 3D几何造型的同步协同设计方法。文章首先分析了网络环境 (尤其是 Internet环境 )下协同CAD系统的特殊要求 ,然后通过比较现有 CSCW系统的同步协同实现方法的不足 ,提出一种基于几何模型层实时通信的协同造型方法 。Collaborative design is a very important research field in network-based CAD/CAM. There are a lot of critical issues to be studied in collaborative design methodology. Our research works focus on 3D synchronous, collaborative geometry modeling. This paper first discusses the special requirements of a collaborative CAD system in network environments. After comparing with the drawbacks of general CSCW synchronous method, a new collaborative modeling technology is presented, which is based on message exchange at geometry model level. Finally, related works in our research are briefly mentioned.
