プロダクトデザイン
Product design is typically a highly iterative and interactive activity involving a group of designers who are geographically dispersed. A neutral modeling commands (NMC) based method is proposed to construct a real-time collaborative product design platform within heterogeneous CAD systems. Different from the visualization-based approaches, models can be constructed and modified synchronously from various sites in the proposed collaborative design environment. Based on a translation mechanism between system modeling operations (SMO) and neutral modeling commands (NMC), every operation given by a user on one site will be translated into a NMC and be sent to all the other sites through the network. When the other sites receive this command, it is converted into corresponding SMOs on the local system. In this way, the real-time collaborative product design with heterogeneous CAD systems is achieved.
