Engineers and designers often need to search out similar CAD models to make reference to and reuse the previous designs. For most of CAD models, both geometrical information and topological information are important for similarity assessment. We proposed two shape signatures to describe the geometry and the topology of a CAD model respectively. A relevance feedback mechanism is introduced to combine the two dissimilarity distances measured by the two signatures. Experiments are conducted to evaluate the performance of the proposed method.
