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.
 Compound Miter — With stored spring (crown)
angle and entered wall corner angle*, consecutive
presses of
 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  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.
Я В Store Spring Angle (Spring Angle) — Stores a
value other than the default spring (crown) angle of
45° (e.g., 3 8 Я В 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 ® В .
