异构CAD系统协同框架与互操作

协同CAD通过网络支持不同地域的设计人员实时地完成产品设计或决策任务,以提高群体协同工作效率;异构CAD系统协同将分布的不同的CAD系统,如ProE、UG、SolidWork等业界比较成熟且是主流的商业CAD系统,集成在一个框架平台下,从而支持人们更方便地协同工作;文章讨论了异构CAD系统协同的体系结构与共享感知问题,提出了一个支持共享感知的复制式系统结构模型;进一步将现有商业CAD系统引入到该模型中,给出了一个基于构件的协同CAD中间件框架模型,讨论了中间件接口和CAD系统的互操作。

Operation Transformation and Collaborative Framework in Heterogeneous CAD Systems

Cooperative CAD supports a group of collaborators from sites connected via the Internet to design or make decisions by the shared CAD data on the same time.Cooperation between heterogeneous CAD systems integrates different CAD systems such as ProE,UG,and SolidWork,which are mature mainstream CAD products in industry,into a collaborative framework platform so as to support convenient work for designer.One of key techniques in the collaborative CAD is real-time shared awareness that supports person-to-person effective cooperation and encourages their creativity or brainstorm and making decisions.First,the system architecture model of the collaborative CAD and shared awareness are discussed,then a replicated system model that supports shared awareness is presented.Furthermore,the above model is introduced into heterogeneous single-user CAD applications and a CAD middleware framework model is proposed based on component with a discussion of related interface design of all parts of the middleware and mutual operation of CAD systems.
