Procedural Representation Based Cross-CAD data Exchange

摘要

The problem of exchanging CAD models together with construction history is a crucial issue to realize a complete Product Lifecycle Management (PLM) strategy in current highly distributed product development environments. The more design data can be re-used effectively, the larger its positive impacts on the overall product lifecycle process. This paper will discuss some theoretic and practical issues that, at present, hinder the exchange of procedurally defined shape models between different CAD systems. Some approaches proposed in literatures are summarized and critically discussed.
