About This Topic

Students solve complex roof geometry problems involving intersecting pitched roofs, dormers, and hip rafters. They determine true lengths and dihedral angles for structural timber cutting.

Key Questions

  1. How do we find the true length of a hip rafter?
  2. What is the dihedral angle between two adjacent roof surfaces?
  3. How are auxiliary views used to solve roof intersections?
