摘　　要：在机械设计中经常会遇到一些形状不规则的零件,这些零件用普通的二维图不易表达,因此需要用到三维建模进行设计,本文将介绍用NX10.0中曲面特征"通过曲线组"在机械设计中应用的实例。文中分析了模型的形状特征,提出了建模方案;介绍了在使用"通过曲线组"时,两个截面形状分别是矩形和圆的情况下,对圆截面的处理方法。此外还介绍了艺术样条的使用方法。In mechanical design,some irregular shape parts are often encountered,which are difficult to express with ordinary two-dimensional drawings,so it is necessary to use three-dimensional modeling for design.This paper will introduce the application of surface feature"through curve group"in nx10.0 in mechanical design.In this paper,the shape characteristics of the model are analyzed,the modeling scheme is proposed,and the processing method of circular cross-section is introduced when using"pass through curve group"when two cross-section shapes are rectangular and circular respectively.In addition,the use of art spline is also introduced.
