Nowadays, there are abundant product models in existence that contain plenty of design knowledge in various disciplines. As an approach to taking full advantages of the existing design knowledge, model reuse plays a more and more important role in complex product design due to the enormous time and cost saving it could bring. To help designers find the right models for reuse quickly and exactly, the content-based assembly retrieval is a promising but still immature way at present. In this paper we present a novel assembly interface representation which captures much more design knowledge in assembly interfaces than plain geometric-matings used most in current CAD models. Then the hierarchical assembly descriptor based on the presented assembly interface representation is described and compared to assembly descriptors in other work. Furthermore, the corresponding similarity assessment method is given to evaluate the distances among assemblies and a complete assembly retrieval method is also described. Finally, an assembly retrieval prototype system is implemented, based on which assembly search samples are analyzed to demonstrate the improved effectiveness brought into the assembly retrieval.
