模块化的STEP模型管理器实现

摘要

In the process of realizing STEP, Application Protocols cann't enough meet the need of specifies domain. To get to this point, a modular approach has been developed. In describes how to apply modular approach in STEP mode l managment, and also defines its information architecture and provides a struct ure of PD-Manager. By PD-Manager user can establish model more expediently. It is flex ible, potentially support integration in different CAx, and sharing between diff erent application areas. Binding with PDM system, product data manage will beco me more flexible.%在STEP模型管理的实现过程中应用模块化方法，定义其内部 结构，并给出了相应的模型管理器（PD-Manager）的实现结构。通过模块化模型管理，使 应 用领域的集成更为方便，并支持产品数据的共享。在与产品数据管理（PDM）系统结合使用 后，提供了一种更灵活支持产品全生命周期产品数据管理的方式。
