Data transfer of hierarchical CAD model based on feature face
基于特征面的分层次CAD模型快速传输*

To solve the problem of high data transmission quantity of shared model in synchronized collaborative design,proposed a data transmitting method of hierarchical shared model based on feature face. By this method,only the triangle facet information was transferred first,the feature faces of components,which would be assembled,would be specified when that parts were to be collaborative assembled,and all feature information of the special feature face were sent. For extracting any feature face in a short time,...
