Measurement of an oblique angle in a plane (measurement type 17)

Measurement of an angle in an inclined plane ($AC_MEAS_TYPE = 17)
The oblique plane is determined using three measuring points P1, P2 and P3.

Meaning
Unless otherwise specified, the reference coordinate for the align‐
ment of the workpiece is always the abscissa of the selected
plane. *
=0: Reference coordinate is the abscissa
=1: Reference coordinate is the ordinate
Unless otherwise specified, the workpiece position angle is en‐
tered in the frame as a rotation. Otherwise, a channel axis index
can be specified for a rotary axis whose translation is set to the
current rotary axis position plus the calculated rotation. The work‐
piece is then aligned at rotary axis position = 0. The current rotary
axis value must be set in $AA_MEAS_POINT[axis]. *
