If you desire, then after the second touch point you can
change the position of the centerline in the evaluation
menu, and thus the axis for setting the preset. Use the
soft keys to choose between principal axis, secondary
axis, and tool axis. This way you can determine the
positions once, and then store them in the principal axis
as well as in the secondary axis.
