探讨了基于特征的减速器零件参数化实体造型其实现方法。基于特征的技术为设计者提供符合人们思维的设计环境；参数化方法使用户构造几何模型时可以集中于概念和整体设计，充分发挥创造性，提高设计效率。把基于特征的技术和参数化方法有机地结合起来进行实体造型将极大地提高设计效率。本文用Ａｕｔｏｌｉｓｐ语言对ＡｕｔｏＣＡＤ２０００进行了二次开发，建立了基于特征的参数化减速器零件实体造型系统，为设计者提供了方便快捷的实体造型支持。
The realization of parameterized entity modeling of reducer parts based on characteristics is discussed. Feature-based techniques provide designers with a design environment that fits people’s thinking. Parametric methods enable users to focus on concepts and overall design when constructing a geometric model, giving full play to creativity and improving design efficiency. The combination of feature-based techniques and parametric methods for physical modeling will greatly improve design efficiency. In this paper, the Autolisp language was used to develop AutoCAD2000. A parametric decelerator component solid modeling system based on the feature was established, which provided the designers with convenient and quick solid modeling support.
