曲面展开CAD系统的设计与研究

Design of Extension Drawing System of Curve Plane

通过建立各种曲面构件的数学模型 ,利用AutoCAD2 0 0 0为平台 ,进行二次开发 ,设计了曲面展开CAD系统 ,从而实现展开图的自动绘制 ,并可用于数控切割加工 .

According to the geometric model of the sheet metal,the extension drawing system of sheet metal has been developed on the basis of AutoCAD by using Autolisp and DCL language.This system can be applied numerical-control cutting process.
