摘要:介绍了一种基于 UG 的零件三维参数化设计技术,根据装配关系区分各类参数,在 UG 中建立三维参数化的零件
模型。用 Visual C++开发主要用于获取参数的应用程序,用 UG 提供的二次开发工具 UG/Open API 开发接口程序,将两
者结合起来,建立实体模型与其尺寸参数之间的联系,实现零件的参数化,自动生成符合用户要求的零件。

Abstract:The article introduces a technique of three dimensional parametric design of part based on UG. According to
assembly relationship, the parameters are differentiated and then three dimensional parametric parts are established in UG.
Using Visual C++, the application is exploited which gets dimensional parameters. Using the method of UG/Open API which is
the quadratics exploitation tool offered by UG, the API program is achieved ,then parts and parameters bined and
relations between models and data are established. Parametric parts are realized, which are accord with user’s requests.
Key words: parametric design;part model;data processing;UG

UG 软件是美国 EDS 公司开发的以机械产品为主的三类( 1)主参数,决定零件装配约束或形状结构的参数。
CAD/CAM/CAE 软件,在国内外机械行业中广泛使用。参数之间是相互独立,由设计者或者应用程序计算确定。
它不但具有强大的设计、制造功能,而且还为用户和第三(2)次参数,其值由主参数决定。主参数确定以后,根
