Abstract: The disclosure relates to method and system for identifying a weldment feature. The method may include extracting a plurality of wire bodies from a sheet-metal model, and identifying from the plurality of wire bodies, a set of wire bodies associated with a face of the sheet-metal model. The method may further include generating one or more potential weldment features from the set of wire-bodies. Each of the one or more potential weldment features may be analyzed with respect to the face of the sheet-metal model. The method may further include identifying from the one or more potential weldment features, at least one related pair of weldment features. Weldment features of each related pair may include one of a contacting relationship and crossing relationship with each other.

Abstract: The invention relates to method and system for automatically identifying tube elements in a Boundary Representation (B-Rep)-based Computer Aided Design (CAD) model of a tube. The method includes extracting information corresponding to the B-Rep-based CAD model of the tube; validating geometrical features of the B-Rep based CAD model of the tube based on the extracted information; classifying each of a plurality of faces of the tube into one of a set of face types; determining one or more regions on the tube using a set of connected top faces of the tube; generating a plurality of primary tube elements and a set of secondary tube elements based on shapes of the plurality of regions; determining a plurality of element parameters for each of the plurality of tube elements of the tube; and determining a plurality of tube parameters for the tube based on the plurality of element parameters.
