摘　　要：对三维CAD模型检索研究现状进行了深入和系统的综述。CAD模型检索可划分为两个层次:基于视觉相似性的三维CAD模型检索、面向语义与功能描述的三维CAD模型检索。分别分析了两种检索层次下CAD模型的检索方法。在此基础上总结了三维CAD模型检索评测基准库、评测方法等。最后展望了现有研究中的难点及进一步的研究方向。A comprehensive survey on the up-to-date retrieval methods for 3D CAD models was presented.Due to the great differences in representations and retrieval algorithms between 3D CAD models and other general models,CAD models retrieval is divided into two hierarchies：visual-similarity-based retrieval and semantic-functional-descriptions-based retrieval.Representations and algorithms of each hierarchy were discussed and analyzed systematically.Benchmarks and evaluations of 3D CAD model searching methods were summarised.Finally existing difficulties and future research were discussed.
