基于三维CAD平台的实时协同设计方法

首先结合三维CAD系统协同设计平台CoopCAD（Pro／E）的开发，探讨了三维协同CAD系统研究中的并发控制、协同感知、网络管理、冲突检测与消解、事务管理和实时性保障等关键技术。然后提出了基于特征的实时协同设计方法，并重点对作为网络间协同信息的三维造型特征的数据结构和基于它的协同设计方式进行了研究。

Method of real-time cooperative design based on 3D-CAD platform

Firstly by combining with the development of cooperative design platform of 3D-CAD system, key techniques in the study of 3D cooperative CAD system such as concurrent control, cooperative perception, network management, conflict detection and elimination, affairs management and real-time safeguard and so on have been probed. After that the method of real-time cooperative design based on features has been put forward, and a study has been carried out emphatically on the data structure of 3D modeling features, which is regarded as cooperative information between networks, and on the cooperative designing mode based on the data structure.
