楼上说的对,就是同一种坐标系,是基准坐标系,又叫datum coordinate system。
9 y/ t8 s- e0 L3 r7 x5 M基准坐标系是啥,我也不太懂。希望懂的能科普下概念。
, Z8 n& G9 p# `( _- H" W4 bNX中如何创建基准坐标系?) w" z- j, C5 K5 B
1,Home tab->Feature group ->Datum SCYS
% m( a( b/ c( Z$ E. |# h! |" @2,在Datum对话框中,在类型上,选择Offset CSYS
7 S- F/ B, u& n: I, ~+ ~/ j3,在参考CSYS组中,从参考的表,选择已经存在的CSYS9 Q+ t, R8 p4 a
4,从grapphics图标中,选择额一个已经存在的datum CSYS9 g1 i4 r7 I$ G& ]9 T) z& p4 q4 j
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. | 1 {: L6 l. b; V% }
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 + m O3 [9 W( O: R1 t( V( i9 m3 ^& l3 B9 b
