   你们会使用CAD绘制机械零件平面图吗？下文小编就讲解CAD绘制机械零件平面图的操作步骤，相信对大家会很有帮助哦。

  1、首先我们绘制的时候要先画中心线，中心线要选择虚线段绘制，在这里我们绘制的虚线中心点与中心点之间的距离我们选择53mm

  2、画好虚线之后我们开始绘制我们需要的零件图形，首先绘制两个大圆，在这里我们分别选择的是直径为17和直径为36的圆

  3、这两个大圆同为一个圆心，然后我们在右边的圆心上画两个小圆，直径分别选取值为8和15 画圆时记得要用实线画

  4、画完小圆之后我们开始绘制连接两个圆的中间的那条线，为了大家方便看，我先画一个外切圆，这个大圆外切与两个小圆，半径为R160

  5、然后我们按照上面步骤再绘制上面的外切线，画好之后用剪切工具减去多余的线，

  6、然后我们再绘制一条128度的直线，115度的直线，一条141度的直线，找到中间孔的中心点，画一个R11的圆，R15的圆，找到两个边，然后绘制两边的圆圆

  7、画好之后看着特别乱吧，没关系我们用剪切工具，把多余的线段都剪掉，都得到下面这个图片了，然后我们不同颜色给它做一个标注就可以了

  上面就是小编带来的CAD绘制机械零件平面图的操作教程，大家都学会了吗?
