@ -5,16 +5,16 @@ Creates a pie (circular sector). You can pass a 2 element vector to define the c
## Parameters
- `radius` : The radius of the circle.
- `angles` : 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.
- `angles` : 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.
- `$fa`, `$fs`, `$fn` : Check [the circle module](https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Using_the_2D_Subsystem#circle) for more details.
## Examples
include <pie.scad>;
pie(radius = 20, angles = [210, 310]);
translate([-15, 0, 0]) pie(radius = 20, angles = [45, 135]);
translate([15, 0, 0]) pie(radius = 20, angles = [45, 135], $fn = 12);
pie(radius = 20, angle = [210, 310]);
translate([-15, 0, 0]) pie(radius = 20, angle = [45, 135]);
translate([15, 0, 0]) pie(radius = 20, angle = [45, 135], $fn = 12);
