In order to better implement the reuse of CAD model, a 3D CAD model retrieval algorithm using ant colony algorithm is proposed.By extracting B-rep information of CAD model, the model is represented by attribute adjacency graph.If there are similar features or local structures in two CAD models, then there should be common subgraph in attribute adjacency graph corresponding to CAD model.The ant colony algorithm is used to detect common subgraphs in attribute adjacency graphs, the local detail features with similarlocal CAD models are obtained.Then CAD models are evaluated by comparing similar local detail features.The experimental results show that the algorithm can achieve 3D CAD model retrieval better, the retrieval performance is higher than the general domain retrieval algorithm, and CAD model design and manufacturing knowledge can be reused.
