基于任务元的工程产品CAD信息对象集成模型

摘要

It is necessary for product info to be communicated,exchanged and shared in engineering design(ED).So it is quite necessary to study collaborative product info.According to feature in ED,the paper presents CAD info object integration in engineering product,with an idea of"task cell",definition of drawing cell object and integration of collaborative links.The experiment in engineering validates the rationality and validity of the ideas.
