The identification of regular patterns of congruent features in CAD models can enrich the object representation by a set of higher level information, which can be exploited for the reuse of the part model. In this paper, a method for the detection of regular patterns and symmetries of repeated subparts in B-Rep part and assembly models is proposed. The method is implemented as a plug-in of a commercial CAD system and detects linear, circular translational, rotational and reflectional patterns of congruent sub-parts of the model.
