Hinge Action -- A Primer

[Yoda]

Here is yet another way to determine hinge action at the 45degree/follow-thru/both arms straight location:

The SCORE LINES point AT the left shoulder = Horizontal Hinge Action
The SCORE LINES point STRAIGHT ACROSS the plane line = Verticle Hinge Action
The SCORE LINES point "In Between" these two points, but on most planes closer to the left shoulder, for Angled Hinge Action

Hadn't heard it put this way before, but it is absolutely correct. SCORE one -- no, SCORE three! -- for Brian!
