Trèteaux Angles: P8m-DP
P8m-DP = Main Side Purlin Rafter Miter Angle On Top Edge Face Perpendicular to Roof Surface
Hip-Valley Roof Ratios Angle Formulas
- P8m-DP = 90
- P8m-DP = 90
The Trèteaux Angles Formulas for Hip Rafters Rotated into the Roof Surface Plane were developed by Sim Ayers and Joe Bartok.
