Abstract: The invention relates to method and system for identifying contact features of Boundary Representation (B-Rep)-based Computer Aided Design (CAD) models. The method includes determining body type associated with body from body types based on information extracted from boundary representation of body; identifying associated body pairs from valid bodies based on proximity between each two of valid bodies and predefined threshold proximity; for each of associated body pairs, identifying face pairs for each body of associated body pairs based on single-body criteria, and for each pair of associated body pairs based on multi-body criteria; and identifying contact features and corresponding contact parameters from each of face pairs based on plurality of user control parameters.
