以网络为中心的语义特征造型协同设计

在网络化同步协同设计环境中，如何实现用户系统之间的实时数据交换、维护特征语义的一致性，成为语义特征造型协同设计的关键问题。该文介绍了基于细胞元表示的语义特征模型，根据该造型技术的分层体系结构，基于对协同环境下特征操作的分析，采取了传输造型操作命令的策略，为解决特征语义一致性问题，提出了一种用操作特征管理器调度操作执行的方法，并给出了一个实例。

Collaborative Design of Semantic Feature Modeling on Network-centric

Within network collaborative design environment, real-time data exchange and feature semantic conformity become a key problem for collaborative design on semantic feature modeling. A semantic feature modeling is proposed, according to the structure of semantic feature model, the strategy of the modeling operation commands being transmitted is adopted. In order to maintain feature semantic conformity, a new method by which OFM is introduced to control operation’s executing is suggested. An example is introduced.
