轴1 的绘制： 创立圆柱体 加凸台并对齐中心 插入基准平面 在基准面上挖键槽 同理可挖另一个键槽 对轴进行必要的倒斜角 2
齿轮轴2 的绘制 输入表达式，输入斜齿轮的各个参数 输入表达式后，插入规律曲线 画齿根圆，分度圆和直线交于分度圆与渐开线 旋转直线 以直线镜像渐开线并以齿根圆，渐开线和另一直线画出封闭曲线 以齿顶圆直径创立圆柱，插入螺旋线并扫掠齿槽 求差 进行特征编组和圆形阵列 以斜齿轮为基础，画齿轮轴，加凸台
插入基准平面，进行绘制键槽 对齿轮轴进行倒斜角 3
齿轮轴3 的绘制 导入表达式并插入规律曲线 画齿根圆，分度圆直线，旋转直线并以直线镜像渐开线 以齿根圆和渐开线画用于扫掠齿槽的封闭曲线 以齿顶圆直
