title: ringSector
---
The `ringsector` macro drafts a ring sector, which is like a part of a donut
with an inside and outside radius. It is particularly useful for drafting
curved waistbands, circle skirts, and so on.
It is provided by the [ringsector plugin](/reference/plugins/ringsector).
:::note
##### Not a core-plugins macro
The `ringsector` macro is not provided by the [core-plugins](/reference/plugins/core),
so you need to load the [ringsector plugin](/reference/plugins/ringsector) explicitly
if you want to use it.

## Signature
```js
macro('ringsector', {
String id='ringsector',
Point center = new Point(0,0),
Number angle,
Number insideRadius,
Number outsideRadius,
Boolean rotate = false,
})
```
## Example
<Example caption="Example of a ring sector drafted by this macro">
```js
({ Point, macro, Path, paths, part }) => {
macro('ringsector', {
angle: 60,
insideRadius: 30,
outsideRadius: 45,
})
return part
}
```
</Example>
## Configuration
| Property | Default | Type | Description |
|---------------:|-------------------|------------|-------------|
| `id` | `ringsector` | String | The id to use in auto-generate macro points and paths |
| `center` | `new Point(0,0)` | [Point][1] | The center point of the ring sector |
| `angle` | | Number | The angle the ring sector should cover |
| `insideRadius` | | Number | The inside radius of the ring sector |
| `outsideRadius` | | Number | The outside radius of the ring sector |
| `rotate` | `false` | Boolean | Whether or not to rotate the ringsector so one of its sides is vertical (see [example below](#example-when-rotatetrue)) |

## Notes
The `ringsector` macro creates a `path` that can be used as a seam path for a part. If doing so, the left side of the path assumes a `cutOnFold`, as the `sa` is not offset here like it is along the rest of the `path`.
### Example when rotate=true
<Example caption="Example of a ring sector drafted by this macro when rotate is truthy">
```js
({ Point, macro, Path, paths, part }) => {
macro('ringsector', {
angle: 60,
insideRadius: 30,
outsideRadius: 45,
rotate: true,
})
return part
}
```
