Nice visuals Martee, just make sure the red and blue arrows are both pointing at the Sweetspot Plane, not the ground. They
appear to the player to be on the ground. But appearance can be deceiving and this is where things can go wrong (this is what Philly and I was trying to say).
The chunky arrow I've used to vandalise your drawing with shows the line the player actually use to Trace (point at) with. That line
is on the ground (and Sweetspot Plane) as the arrow shows. Remember, there can only be
one line that lies on the ground
and on the Sweetspot Plane (if you don't believe me, try find another one
)
Now, can the player use the Impact Point Plane Line or the Low Point Plane Line to Trace with? Yes, with but great caution, because as long as one thinks these alternative lines are on the ground (rather than above or below the ground), they will be tracing the wrong line!
Newbies reading this may be scared of Tracing now because they think it's so complicated. Forget it! You are probably Off Plane by 12 inches, and what we're talking here is a couple of inches max. Just draw a straight line through the white round thing and trace that line.
