NX中如何创建基准坐标系?

& E w4 ?9 n. T2 H v$ ?2,在Datum对话框中,在类型上,选择Offset CSYS V/ k" O3 Q) x
3,在参考CSYS组中,从参考的表,选择已经存在的CSYS
# T# D5 {7 `: W5 p" s- g% N+ |7 _4,从grapphics图标中,选择额一个已经存在的datum CSYS, i( O! J! g/ }3 W3 y3 a. I
5,In the Offset from CSYS group, type the required translation and rotation parameters. Note | The translation and rotation parameters are stored with the datum CSYS feature and can be edited as expressions. | - a7 d6 Z3 e$ Q0 |
Click OK or Apply to create the datum CSYS. For this example, the following are used: X=75, Y=200, Z=50, Angle Y=25
