RationalDMIS 7.1 旋转和平移坐标系
1.第一步：
找正（确定坐标系第一轴）
注意：可以用来找正的元素：平面、圆柱、圆锥。
2.第二步：
旋转（确定坐标系第二轴）
第二基准：通过直径15mm孔和直径12mm孔的轴线（两孔最佳拟合直线）
可以用来旋转的元素：直线、 圆柱、圆锥等。可简化为线元素或者构造为线元素的线性元素。
3.第三步：
平移（确定坐标系原点）
可以平移的元素 一般为点元素或者圆等可以简化为点元素的点形元素。
4.第四步：
通过输入角度绕Y轴做附加旋转。
通过输入图纸上的角度进行坐标系旋转。这个角度可以通过正切函数计算。绕Y轴旋转，输入29.25°。
注意：也可以使用高级功能三角函数输入。
在该例子中：输入ATAN（14/25）*3.1415926/180或RTOD(ATAN2(14,25))
5.第五步：
将坐标系平移到两个孔中间：
