Abstract
Methods, systems, and apparatus, including medium-encoded computer program products, for computer aided design of physical structures include: obtaining a B-Rep model including parametric surfaces and associated coedges; generating feature matrices from the coedges associated with the parametric surfaces; using the feature matrices in a convolution layer of a convolutional neural network of a machine learning algorithm to recognize a collection of faces or edges in the B-Rep model, including concatenating results of transforming the feature matrices using a topological walk matrix that represents topological information for the parametric surfaces based on adjacency relationships among the coedges (e.g., including ordering information); and preparing, based on the at least one collection of faces or edges recognized by the machine learning algorithm, (i) a display of the B-Rep model to facilitate user changes or (ii) a design of the B-Rep model to facilitate manufacturing a physical structure using the B-Rep model.
