虚拟企业基于STEP的三维协同设计研究

Three dimension cooperation design on virtual enterprise based on STEP

通过对基于网络的协同设计结构进行深入的分析 ,确定了以各种典型CAD系统为设计支撑平台 ,以STEP交换文件作为信息传递的方式 ,利用NetMeeting对整个协同设计小组进行管理的三维协同设计系统结构。可以实现各协同设计者对产品数据的实时共享 ,使设计从传统上的”人 -机”交互转变到设计者之间的”人 -人”交互。能够充分利用现有资源、缩短产品的研发周期 ,从而实现异地基于三维、声音。

The paper discusses the cooperation design based on internet,gets conclusion in case of taking all kinds of CAD system as designing platform,taking STEP exchange file for transfer mode, using NetMeeting to manage the whole cooperation group method. The data processed can be shared by every cooperation designer, So the traditional meaning of 'man-computer' interaction for design are converted to 'man-man' interaction. As a result,we can make full use of the available resource and shortening the design cycle of product. Thereby it is possible to realize cooperation design on three-dimension graph, audio, and video.
