Degree Of Pitch; Percent Grade - Calculated Industries Sheet Metal/HVAC Pro Calc User Manual

Plumb: Vertical Cut. The angle of cut from the edge of the board
that allows the rafter to mate on the vertical side of the ridge rafter.
Level: Horizontal Cut. The angle of cut from the edge of the board
that allows the rafter to seat flat on the wall plate.
Cheek: Side Cut(s). The angle to cut from the SIDE of the Jack
rafter to match up against the Hip or Valley rafter, usually made by
tilting the blade from 90°. Jack rafters typically have one Cheek cut.
If there is only one Pitch (no Irregular Pitch), the angle will be 45°. If
there are two Pitches, each side will have a different Cheek cut for
the Jack rafter and the angles will total 90°.
