Roof Framing Geometry Propositions – Axioms #3

Added a new Axiom to the Roof Framing Geometry Propositions. This one is for two rotated hip rafters for the angle on the bottom of the intersecting hip rafter.

Roof Framing Geometry Proposition – Axioms # 7:
A line from the intersection of the DP lines of two Hip Rafters, "a", to the hip rafter slope line "b" following the DP line, with a length equal to an arc length of the side face of the hip rafter lower claw length will determine point "c", for the angle on the bottom of the rotated hip rafter.

Unfolded pattern for the head cut on the rotated hip rafter intersecting the rotated hip rafter.
