A set of CAD assembly test models to evaluate component interfaces using CAD assembly modules

Set of 3D CAD assembly models in STEP AP 203 format. Assembly test models are devoted to evaluations of interfaces between components. The interfaces can be of type surface, rectilinear contacts, circular contacts, or punctual contacts. The content and use of the test models are described into the pdf document: A set of CAD assembly test models to evaluate component interfaces using CAD assembly modules, available with the test models.本数据集收录采用STEP AP 203格式的三维计算机辅助设计（Computer Aided Design, CAD）装配模型。该装配测试模型专用于评估组件间的交互界面，此类界面可分为曲面接触、直线接触、圆周接触与点接触四类。 本测试模型的内容与使用说明详见随测试模型一同提供的PDF文档：《采用CAD装配模块评估组件交互界面的CAD装配测试模型集》。
