Returns shape points of an arc shape. They can be used with xxx_extrude modules of dotSCAD. The shape points can be also used with the built-in polygon module.
radius: The radius of the circle.
angle: A single value or a 2 element vector which defines the central angle. The first element of the vector is the beginning angle in degrees, and the second element is the ending angle.
width_mode: The default value is
"LINE_CROSS". The arc line will move outward by
width / 2and inward by
width / 2. If it's
"LINE_OUTWARD", The arc line moves outward by
"LINE_INWARD"moves the arc line inward by
$fn: Check the circle module for more details.
