# arc
|
|
|
|
Create an arc. You can pass a 2 element vector to define the central angle. It provides a `fn` parameter consistent with the `$fn` parameter of the circle module. It depends on the `circular_sector` module so you have to include circular_sector.scad.
|
|
|
|
## Parameters
|
|
|
|
- `radius` : The radius of the circle.
|
|
- `angles` : A 2 element vector which defines the central angle. The first element of the vector is the beginning angle in degrees, and the second element is the ending angle.
|
|
- `width_mode` : The default value is `"LINE_CROSS"`. The arc line will move outward by `width /2` and inward by `width / 2`. If it's `"LINE_OUTWARD"`, the arc line moves outward by `width`. The `"LINE_INWARD"` moves the arc line inward by `width`.
|
|
- `fn` : The `$fn` value used by the `circle` module internally. The default value is 24.
|
|
|
|
## Examples
|
|
|
|
arc(radius = 20, angles = [45, 290], width = 2);
|
|
%circle(r = 20, $fn = 24);
|
|
|
|
|
|
|
|
arc(radius = 20, angles = [45, 290], width = 2, width_mode = "LINE_INWARD");
|
|
%circle(r = 20, $fn = 24);
|
|
|
|
|
|
|
|
arc(radius = 20, angles = [45, 290], width = 2, width_mode = "LINE_OUTWARD");
|
|
%circle(r = 20, $fn = 24);
