Cdesign (Collaborative Design)系统的设计目标是建立一个异地协作设计的支撑环境。论述了基于 Web的异地协作设计系统 Cdesign的意义及其基本框架。 Cdesign系统采用 CL IENT/ SERVER的结构构建 ,客户与服务器的交互主要通过 WWW方式来实现。在此基础上 ,进一步分析了Cdesign系统的主要功能模块 ,给出了管理模块、协作模块、安全模块等模块的具体实现方案 ,并讨论了尚存在的主要技术问题。设计人员可以使用 Cdesign系统交流设计思想、讨论设计方案。通过协作设计专用软件设计人员还可以进行实时的共同设计 The design goal of Cdesign (Collaborative Design) system is to establish a supporting environment for collaborative design in different places. The significance and basic framework of Cdesign, a collaborative design system based on Web, are discussed. Cdesign system uses CL IENT / SERVER structure to build, customer and server interaction mainly through WWW way to achieve. On this basis, the main function modules of Cdesign system are further analyzed, and the concrete implementation schemes of management module, cooperation module and security module are given, and the main technical problems still exist. Designers can use the Cdesign system to communicate design ideas and discuss design options. Through collaborative design of dedicated software designers can also conduct real-time co-design
