METHOD AND SYSTEM FOR IDENTIFYING MULTI-LEVEL THROUGH POCKET FEATURES FROM BOUNDARY REPRESENTATION (B-REP) MODELS

原文（中国語）

This disclosure relates to method and system for identifying through pocket features having a non-unique entrance face from B-Rep models. The method includes receiving a user input including a B-Rep model. The method further includes identifying a reference shell face from the plurality of faces and an associated reference shell edge based on reference identification criteria. The reference shell face includes the reference shell edge. The method further includes sequentially identifying a set of consecutively adjacent shell faces from remaining of the plurality of faces and a corresponding set of shell edges based on subsequent identification criteria. The method further includes validating a loop formed by the reference shell face and the set of consecutively adjacent shell faces based on through pocket validation criteria.
