Coding of Topological Entities in Feature-Based Parametric Modeling System

摘要

How to identify topological entities during rebuilding features is a critical problem inFeature-Based Parametric Modeling System (FBPMS). In the article, authors proposes a new codingapproach to distinguish different entities. The coding mechanism is expatiated, and some typicalexamples are presented. At last, the algorithm of decoding is put forward based on set theory.
