the setpoint of the center point of a hole, shaft, or rectangle, or for the center of a groove,

This value is also entered in the following result array:

• _OVR[1], _OVR[2] (for hole, shaft, groove, web).

• _OVR[2], _OVR[3] (for rectangle).

Specification of measuring axis:

The measuring axis in _MA only has to be specified for web or groove:

• _MA=1: measurement in abscissa
