基于特征重排的协同设计系统研究

随着协同虚拟环境概念的提出，使得多用户之间基于特征的建模设计成为可能并迫切需要一个有效、灵活并支持异地分布的多用户协同工作的系统。在文献2]提出的特征重排思想的基础上对协同设计系统进行研究，提出了一个基于特征重排的协同设计应用系统模型，详细探讨了模型系统的结构，重点阐述了该系统模型中当用户不按照初始设计顺序提交特征造型信息时，服务器如何依据特征重排的思想对特征进行布尔操作保持与原始造型一致，这对于提高协同设计的效率有重要意义。

Research of Feature-Rearranged Collaborative Design System

The emergence of concept of CVE makes collaborative feature modeling among multi - users possible and arises the urgent needs of developing system to support collaborative work of multi - users distributed at different places efficiently and vividly. Presents a model of collaborative design system according to the method of feature- rearrangement given in reference2]. Architecture of the model is discussed in detail, and the approach of how to make the result model be consistent with the required model after the Boolean operation on server when the order of the submitted features are different from the original design order is introduced. This model is important for improving the efficiency of collaborative design.
