Layover Valley Rafter Hexenschnitt #4

Apparently, I had drawn the roof surface incorrectly in the previous drawings of the Layover Valley Rafter. The incorrect roof surface angles affected the Layover Valley Rafter Hexenschnitt angle. After drawing the correct folding roof surface the Hexenschnitt geometry for the foot of the Layover Valley Rafter works correctly. It's actually pretty simple.

Revised drawing of the Layover Valley Rafter Hexenschnitt with the correct folding roof surface.

Here's another way of drawing the Layover Valley Rafter Hexenschnitt. It was sent to me by Bernd  Brück. The two drawings look different, but they're both using the same geometric principles to define the intersecting planes for the Layover Valley Rafter Hexenschnitt cut.
