参数化零部件库建库技术研究与实践

在论述特征、事物特征表、特征造型与参数化设计的相互关系的基础上， 提出了基于通用CAD 系统的参数化零部件设计思路。在研究Inventor 平台二次开发的基础 上，提出了基于Inventor 的参数化零部件库的构建方法和关键的实现代码，并通过实例验证 了该方法的可行性。

Research and Implementation of Parametric Parts and Components Library

On the basis of describing the relationship between features, tabular layout of article characteristics, design with features and parametric design, the paper proposes an insight into how to parameterize parts/components on general CAD systems. Based on the research of customized development on Inventor, the methodology of building parametric parts/components library and developing key implementation code on Inventor is put forward. Instance of case study is performed and demonstrates the feasibility of the methodology.
