研究集成环境下的产品建模和特征模型一直是制造领域的热点。本文在现有特征建模的基础上，提出一种新型的集成型建模系统，设计了实现产品信息集成的特征转换机制，建立了三层组织的产品模型结构，最后讨论作为信息建模和特征转换的基础——元特征的构造。 It has been a hot area in the field of manufacturing to study the product modeling and feature model in the integrated environment. Based on the existing feature modeling, this paper proposes a new type of integrated modeling system, designs the feature transformation mechanism for product information integration, establishes the product model structure of the three-tier organization, and finally discusses the model of information modeling Foundation of Feature Transformation - Construction of Meta Features.
