DESIGN AND IMPLEMENTATION OF SYNCHRONIZED COLLABORATIVE SYSTEM UPON HETEROGENEOUS CAD SYSTEMS

摘要

The synchronized collaborative design within heterogeneous CAD systems becomes a significant challenge because of the great differences in the modeling operations and underground data structures between different CAD systems. This paper first proposes a collaborative architecture with heterogeneous CAD systems, which is composed of CAD Adapter component and CoCAD Middleware component. The CAD Adapter is responsible of capturing of local operation commands and replaying of remote operations, and the CoCAD Middleware takes charge of translation of operation commands between different CAD systems based on a language of neutral modeling command (NMC). The system design and prototype of synchronized collaborative design is discussed based on two common CAD systems Pro/E and UG with their APIs and VC++.
