Pitch Ratio or Slope — Enters the pitch as a ratio
or
slope of a roof (or right triangle). For example,
0.58 slope is entered as
• 5 8 Ç p
.
r
Enters or calculates the
rise or vertical leg (height)
of a right triangle.
R
Enters or calculates the
run or horizontal leg (base)
of a right triangle.
d
Diagonal — Enters or calculates the diagonal leg
(hypotenuse) of a right triangle. Typical applications
are “squaring up” slabs or finding common rafter
lengths. Additional presses of the
d
key will also
display plumb and level cut angles in degrees.
Note: The Common rafter calculation is the “point-to-point” length
and does not include the overhang or ridge adjustment.
Hip/Valley and Jack Rafter Keys
The
Construction Master Pro uses the rise, run, diagonal, pitch and
on-center spacing values to calculate
regular and irregular hip/valley
and jack rafter lengths (excluding wood thickness, etc.).
