B-Reps models are represented as complicated network of topology and geometry that will pose difficulties in the recognition of features. To simplify the search process, heuristic reasoning is adopted. Reasoning on topology will search and define the features, and geometry data are then used to extract the geometrical properties. This search process will identify features emanated from inner loops that lead to the recognition of island, pocket, and through pocket. Since the search is mainly based on the topology, the orthogonal and non-orthogonal features can be identified using the same procedure. Then, heuristics reasoning is again applied to features especially nested of pocket and island as well as isolated island to convert the design feature into machining features. Features such as pocket and through pocket and a new feature which is called prismatic ring are identified. The implementation of heuristic reasoning to recognize isolated design features with the aim to recognize machining will simplify the search process on the complicated of B-Reps data. The focus of this paper is to demonstrate the application of heuristics reasoning by showing the programming algorithm based on Visual Basic Language (VBA) using Application Programming Interface (API) of Solidworks CAD software.References
