hip roof cap revisited

hip roof cap revisited

RE: hip roof cap revisited

The procedure is the same for a hip or a valley, i.e. find the vector normal to each plane, then take the dot product of the normal vectors to find the angle.

If A and B are the normal vectors of the two planes, then A.B = |A||B|cosθ or cosθ = A.B/|A||B| where θ is the angle between the two planes.

It doesn't matter whether the two planes meet on a hip line or a valley line, the angle is the same.
