Design of the Improved PDM and the Real-time Collaborative Viewing System

Abstract

AbstractThis paper describes design methods of the improved PDM and the real-time collaborative viewer. The improved PDM system is designed based on UML. Database Searching speed on the network and automatic creation of UI through the UI builder have been studied in this paper. The real-time collaborative viewer has been designed to eliminate network dependency. It reduces the cost of implementation and management of the system. As the developed system is lightweight, it runs on all types of networks from high-speed LANs to wireless connections. Collaborators can check dimension errors, human factors, form errors, as well as mark up the important parts and deliver messages of their views over the Internet. Functions of 2D and 3D data viewing, markup and annotation, dynamic sectioning, printing services, and real-time conferencing combined with the PDM render real-time benefits to reduce production time to market and design cost. The usefulness of the developed system is confirmed through case studies.
