楼上说的对,就是同一种坐标系,是基准坐标系,又叫datum coordinate system。
- j0 V' S, \, G; ~ \8 F6 h. Y基准坐标系是啥,我也不太懂。希望懂的能科普下概念。
) q5 W- J1 `, N' f+ ]NX中如何创建基准坐标系?2 e6 w( o/ _. V7 l4 a/ \+ |/ J
1,Home tab->Feature group ->Datum SCYS
& N1 L; e9 H3 h2 w. x2,在Datum对话框中,在类型上,选择Offset CSYS
8 X$ y& R0 k* f3,在参考CSYS组中,从参考的表,选择已经存在的CSYS
, |( l! U; W% R7 N3 m4 v9 c4,从grapphics图标中,选择额一个已经存在的datum CSYS
3 t0 k8 m9 ^8 j8 a$ h2 c5,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. |
3 Q6 _/ H7 l S" H9 d' {& G/ H+ \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
