In this paper, we present a survey of existing approaches on persistent naming in parametric system. We identify five common concepts that may be found in most of the studies. We propose two orthogonal criteria for classifying persistent naming approaches. This survey is intended to represent a state of the art of robust parametric reevaluation of geometric(More)
Nowadays, many commercial CAD systems support history-based, constraint-based and feature-based modeling. Unfortunately, most systems fail during the re-evaluation phase when various kind of topological changes occur. This issue is known as " persistent naming " which refers to the problem of identifying entities in an initial parametric model and matching(More)
Nowadays, many commercial CAD systems are built on proprietary geometric kernel which provide an API containing a set of high level geometric operations (boolean operations, slot, chamfering, etc). Because of their complexity, these operations can generate important modifications on topological cells (vertices, edges, faces, volumes, etc.) of the objects.(More)
