Starting with version 2.0, BuildCalc's Arc function has been enhanced
to display the most information with the least number of
keystrokes. Because the first press of the [Arc]
key is often used to store an arc length or arc angle value for other calculations, no change has been made in
function for the first key press. However, if the [Arc] key is
pressed a second time, all Arc function results are displayed in a list.
The Arc function calculates the descriptive geometry for an arc when given two of the following* as inputs:
The Arc function also calculates the length of each stud required to
frame an arch. In addition to two of the above values, this
portion of the calculation depends upon the following stored values or
settings:
Switches between arches that are framed on the outside vs. framed on the inside.
The extra base length added to every stud.
