# shape_pie
|
|
|
|
Returns shape points of a pie (circular sector) shape. They can be used with xxx_extrude modules of dotSCAD. The shape points can be also used with the built-in polygon module.
|
|
|
|
## Parameters
|
|
|
|
- `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.
|
|
- `$fa`, `$fs`, `$fn` : Check [the circle module](https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Using_the_2D_Subsystem#circle) for more details.

|
## Examples
|
|
|
|
use <shape_pie.scad>
|
|
|
|
shape_pts = shape_pie(10, [45, 315], $fn = 24);
|
|
polygon(shape_pts);
|
|
|
|
|
|
|
|
use <shape_pie.scad>
|
|
use <helix_extrude.scad>
|
|
|
|
shape_pts = shape_pie(10, [45, 315], $fn = 8);
|
|
|
|
helix_extrude(shape_pts,
|
|
radius = 40,
|
|
levels = 5,
|
|
level_dist = 20
|
|
);
