Column/Cone Function
The Column and Cone function helps you quickly estimate volume
and surface area of columns or cones.
Ç C
Column and Cone (Column/Cone)
— With an
entered diameter and height, the first and second
presses of
C
(following
Ç
) will calculate the
total volume and surface area of a Column ; the third
and fourth consecutive presses of
C
calculate the
total volume and surface area of a Cone .
For Trig Model (#4080) Users:
As this model does not have a
h
key, you must enter the height using the
r
key.
Compound Miter/Crown Moulding Keys
The Construction Master Pro also calculates compound miter cut
angle solutions for cutting and installing crown moulding on a wall.
The Compound Miter function can also be used for finding angle
cuts for many types of compound miter problems, such as siding,
railing and trim.
Â
Compound Miter
— With stored spring (crown)
angle and entered wall corner angle*, consecutive
presses of
Â
will calculate the following:
Press Result
1
Miter Angle (MITR)
2 Bevel Angle (BEVL)
3 Redisplays Stored Spring Angle (SPRG)
4 Redisplays Entered Wall Corner Angle (CRNR)
* Wall Corner Angle entries of less than 25 into
Â
will be
assumed to be the number of sides of a polygon; in this case, the
calculator will calculate the unknown Wall Corner Angle first, then
proceed with the above angle calculations.
ß Â
Store Spring Angle (Spring Angle) — Stores a
value other than the default spring (crown) angle of
45° (e.g.,
3 8 ß Â
stores 38° spring angle).
This value is permanently stored until you change it
or perform a
Clear All (
Ç x
). To recall the stored
setting, press
