巧用AutoCAD绘制机械工程图样——以阶梯轴绘制为例

On Drawing the Mechanical Engineering Figures by AutoCAD——Taking the Stepped Shaft Plane Figure as an Example

阶梯轴是机械传动中的重要零件之一,在机械制图表达中经常以一个主视图、若干个断面图、剖视图或局部放大图组成。本文基于Auto CAD软件通过镜像命令、矩形命令和偏移命令三种方法绘制阶梯轴平面图形,总结了Auto CAD在绘制阶梯轴平面图形中的一些实用技巧,为机械工程图样的绘制提供参考。

The stepped shaft is one of the most important parts in mechanical transmission.The drawing of a stepped shaft is always made up of a front view, several sectional drawings, cutaway views or enlarged partial views.By means of the Mirror Command, the Rectangle Command and the Migration Command of the AutoCAD software, the stepped shaft plane figure is drawn.Some practical techniques in drawing the stepped shaft plane figure by the AutoCAD are concluded, which provide references for drawing mechanical engineering figures.
