A Persistent Naming Discrimination Method Based on the Sweeping Direction

So far, China's high-end industrial field in industrial software design, research and development is still a blank. To fill the blank, the project called “Wukong” has been carried out by ZWSOFT company. One of the requirements of high-end industrial design software is strong modeling stability. The problem of persistent naming of topological elements is a basic problem to be solved in the current parametric system. In view of academic research and commercial parametric modeling software, there is still ambiguity and instability in the persistent naming of symmetric topological elements. In order to improve the modeling stability and reduce the ambiguity of persistent naming, a persistent naming discrimination method based on the sweeping direction is proposed. The method has both conceptual rigor and theoretical rigor. It has been applied to Wukong. Experiments show that the proposed method is more stable than UG and CATIA in modeling scenarios with symmetric split faces. Therefore, it is believed that the parametric modeling stability can be improved by this method.
