Considering the characteristics of cooperative virtual assembly process, the product feature information is classified in this paper. A precision-oriented cooperative virtual product assembly model is presented based on the tolerance expression of the part feature. The model includes four layers: the hierarchical relation layer, the connectivity relation layer, the feature layer and the feature element layer. With the help of the relation chain within each layer and the mapping information between the layers, different engineering information is integrated. Finally, a new algorithm of automatic generation of dimension chains in cooperative virtual assembly environment is described by using searching mechanisms.
