To Define an ACS with Data Points
Select the Define ACS by Points tool ( split button).
- Enter a data point to define the ACS origin.
- Enter a data point to define the direction of the ACS's positive x-axis, which extends from the origin through this point.
(3D only) Enter a data point to define the direction of the positive y-axis.
The direction of the positive z-axis follows by applying the right hand rule.
