我是靠谱客的博主超级白开水，最近开发中收集的这篇文章主要介绍RationalDMIS 2020旋转和平移基本坐标系，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

演示如何通过给定角度旋转坐标系，如何在笛卡尔坐标系中进行平移。

主基准（空转轴）：立方体前表面

第二基准（面转轴）：

通过直径15mm孔和直径12mm孔的轴线

然后按照第二步逆时针旋转

X零点（原点）：直径15mm孔

Y零点（原点）：平面

Z零点（原点）：直径15mm孔

平/旋按照图纸给定值操作

1.第一步：

如图对主基准，X，Y，Z原点进行设置。

不设置第二基准

Y轴平行于平面法向

F(PLN1)=FEAT/PLANE,CART,27.5264,0.0000,10.2336,0.0000,-1.0000,0.0000
$$ Measurement points are created through nominal points
MEAS/PLANE, F(PLN1), 4
  PTMEAS/CART,  -7.6391, 0.0000,  25.4170, 0.0000, -1.0000, 0.0000
  PTMEAS/CART, -10.2665, 0.0000, -11.2614, 0.0000, -1.0000, 0.0000
  PTMEAS/CART,  63.1667, 0.0000, -13.0719, 0.0000, -1.0000, 0.0000
  PTMEAS/CART,  64.8444, 0.0000,  39.8506, 0.0000, -1.0000, 0.0000
ENDMES
 
D(CRD1) = DATSET/FA(PLN1), -YDIR
D(CRD1) = TRANS/YORIG, FA(PLN1)

2，第二步：旋转轴向，平移三轴原点。

测量两圆，最佳拟合直线。

前面设定的坐标系绕Y轴，绕15mm孔圆心旋转，使X轴通过直径12mm圆的加以，原点位置保持不变

3.第三步：

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

将坐标系平移到两个孔中间：

X=25 Z=14
