Creating a Spiral Stair with User-Specified Settings
Use this procedure to create a circular sweeping and spiral stair. A spiral stair
revolves about a common center point from bottom to top.
You can specify a radius directly or on the screen only when the arc constraint
is free. Otherwise, the radius is determined from the specified tread length
and arc constraint. In that case, you need to adjust the tread length to achieve
the desired radius.
