Calculates the outside (default) and inside lengths of arched walls. The outside arched wall lengths are measured outside of the arc. The inside arched wall lengths are measured inside of the arc.

Examples:

1. Find the radius of an arched window with a chord length of 8 Feet 1 Inch and a rise of 2 Feet and 10-1/2 Inches. Then, find the arc angle, arc length, and segment area of the window. Then, find the "outside" arched segment wall lengths in order to frame the window.

2. You're building a circular or arched segment wall. Given a chord length of 15 Feet and a segment height of 5 Feet, find all arc values and "inside" arched segment wall lengths. The On-center spacing is 16 Inches.

In the following example, you will change the arched wall preference setting to Inside before following the keystroked example. To access Preferences:
