Elliptic Roof Sketches
Elliptic Roof Calculator
Dimensions are to the theoretical Framing Points and backed Hip rafter ridge lines
There are no corrections for the Hip Drop, overhang at the soffit, H.A.P., etc.
Enter Hip Runs in the SSS Triangle Calculator to double-check Deck Angles
Enter Hip Lengths in the SSS Triangle Calculator to double-check Roof Plane Angles
Arc Length and other ellipse data can be solved using the Ellipse Calculator
