Since the current retrieval algorithms cannot describe local features of CAD models detailed in the CAD field,a new one of 3D CAD model retrieval based on maximum common subgraph is proposed.Extracting B-Rep information of CAD models,the models are represented by the attribute adjacent graph(AAG).If two CAD models contain similar sub-parts,the corresponding AAGs ought to have common subgraph.According to this principle,the similar sub-parts are obtained by detecting the common subgraph of AAG.The similarity of the CAD models is evaluated by comparing the similar sub-parts.The experimental results show the efficiency of 3D CAD model retrieval to meet the requirements of engineering retrieval and reuse of design and manufacture.
