Abstract: To establish collaborative perception between model level and feature level of relevant design models, the router perception description table at the Product Data Management (PDM) node was maintained to map the models across the distributed heterogeneous Computer Aided Design(CAD) platforms. The model feature correlation description table at the CAD node was maintained to map the model features among CAD models, at the same time the modification of master model was encapsulated by a description table. The collaborative model perception and feature perception could be realized through the geometry modification search algorithm and feature location modification algorithm. Finally, the model feature correlation modification description table was established to encapsulate the correlation modification among CAD models. And the collaborative adaptation algorithm was used to update the collaborative perception map of the design models.
