MEASURE_AXIS_3D measures a specified axis in the global 3D coordinate system. An axis consists of a 3D point and a direction.
If the system is being used interactively, the value is displayed in the MEASURE Output Field. By using OK the values can be used without retyping. The value is also written into the system inquiry array (see INQ).
