Paper Abstract

Feature recognition from geometric modeling systems plays an important role in the attempt of integrating CAD and CAM systems. The non-unique tree representations of a CSG solid modeler, however, can make a recognition process very complex. In this paper, three major reasons leading to the non-uniqueness are examined, and the most commonly occurring one is dealt with in detail. Based on the achievement of position relationships between orthogonal primitive objects, an approach for solving the non-uniqueness stemming from multiple definitions for an identical object is presented.
