[T1R] Where is the [0,0,0] Point in P2P mode?

The P2P origin is a straight line between the red laser point and the modifier active at the time of measurement (where the line intersects that plane).

For example, if the laser were shining at a surface and the device being its its laser default of “Measure Back,” the 0,0,0 point would be the straight line distance from the laser point on the surface to the laser intersection with the back of the T1R. The below diagrams show where this point would be if in "Measure Back" mode (in mm).
