$AA_MEAS_POINT2[axis] Measuring point 2
$AA_MEAS_POINT3[axis] Measuring point 3
$AA_MEAS_SETANGLE[axis] Setpoint rotations around abscissa and ordinate *
$AC_MEAS_ACT_PLANE Calculated as active plane unless otherwise specified *
$AC_MEAS_FRAME_SELECT Calculated as additive frame unless otherwise specified *
$AC_MEAS_T_NUMBER Calculated as active T unless otherwise specified (T0) *
$AC_MEAS_D_NUMBER Calculated as active D unless otherwise specified (D0) *
$AC_MEAS_INPUT[0] Unless otherwise specified,
the points are not projected in a plane *
0: Points are not projected on a plane
1: Points are projected in the active plane or in the selected
plane
