| 摘 要： | 该文研究了基于STEP的CAD系统集成方式和传统CAD系统间协同工作方式,并在自主开发的CAD系统GHMDS4.0的体系结构的基础上提出了一种分布式的基于STEP的CAD协同工作的同步协同工作方式,从而为CAD协同工作提供了一种新的思路。最后文章还提出EXPRESS数据库差分方法以减少通讯中的数据量。

| Abstract: | In this paper,a method of STEP based CAD systems integration is provided,and traditional asynchronous cooperative work among CAD systems is summarized by petri net.Based on the software architecture of a CAD system,GHMDS4.0,developed by ourselves,a method of distributed synchronous STEP based cooperative work among CAD systems is proposed,which provides a new idea to CAD cooperative work.Furthermore,in order to overcome the current slow transmit rate,EXPRESS databases difference is proposed to reduce communication data. |
