Verkanteter Gratsparren

Verkanteter Gratsparren translates to canted hip rafter in German. In these drawings the canted hip rafter is rotated into the roof surface plane on a ground plan with equal roof slope angles and the eave angle is 60°. This example uses my Roof Framing Geometry Propositions – Axioms on a jack rafter that's plumb to the earth and the German Shiften method for locating the upper and lower claw angles from the width of the jack rafter in plan view.
