在AutoCAD R14中螺旋体的建模方法及其参数化设计

Methods of Helicoid Modeling and Parametrization Design Using AutoCAD R14

提出用AutoCADR14的三维造型功能建立螺旋体模型的方法，并利用AotoLISP语言通过二次开发实现螺旋体的参数地设计，从而扩展了AutoCADR14的三维造型功能。该参数化设计应用程序可以建立各种截面形状的螺旋体模型，具有灵活性和通用性，为有关应用领域提供了方便。

The methods of the helicoid modeling were developed using the 3-D design function of the AutoCAD R14. The parametrization design of the helicoid has been realized by using the AutoLISP. The 3-D mould-making function, therefore, of AutoCAD has been extended. The helicoid model with different shapes of sections can be built by the methods presented in this paper.
