Intersecting Roof Slope Angle = arctan((Main Pitch - Dormer Pitch) ÷ 12) Dormer Height = Dormer Height Above Main Roof + Dormer HAP Main Roof Rafter Intercept Length = (Dormer Height ÷ tan(Intersecting Roof Slope Angle) ) ÷ cos(Main Roof Pitch Angle) Dormer Run = Dormer Height ÷ tan(Intersecting Roof Slope Angle) Dormer Rafter Length = Dormer Run ÷ cos(Dormer Roof Pitch Angle) Dormer Miter Cut Angle = Main Roof Pitch Angle - Dormer Roof Pitch Angle

The book includes step by step instructions on developing stereotomic drawings on Art du Trait de Charpente, Trestles, Tréteau à devers, Canted Trestles, Louis Mozerolles' Joiners Table, Sawhorses, and the Saint Andrews' Cross, twisted crosses. You'll also find theories on hip rafter shift-offset, standard roof framing kernel trait drawings, German Schiften DP-Shadow Line techniques, folding net roof surface and net plane geometric development, when hip rafters collide, the Warlock Cut, and developing upper and lower claws on rafters using Axioms.
The book includes step-by-step instructions on developing stereotomic double curvature drawings for circular work in carpentry. Some of the techniques presented in this book are thousands of years in the making. As carpenters, we shouldn't have to re-invent the wheel each time we are faced with new challenges. There is a likely hood that someone, that came before us, has already refined a technique that we can use today. The tools might have changed, but the piece of wood that it is twisting and turning remains the same piece of wood.
