title: sewTogether
---
The `sewTogether` macro is used to mark where two parts of the same `part` need
to be sewn together. This happens when you want to construct a cone for instance.
It is provided by [plugin-annotations](/reference/plugins/annotations), which is
part of [core-plugins](/reference/plugins/core) (so it is available by default).
## Signature
```js
macro('sewTogether', {
String id = 'sewtogether',
Point from,
Point to,
Point middle = null,
Boolean hinge = false,
String prefix = 'sewtogether',
Boolean force = false,
})
```
## Example
<Example caption="An example of the sewtogether macro">
```js
({ Point, points, Path, paths, macro, part }) => {
points.seamTL = new Point(0,0)
points.seamM = new Point(30,-10)
points.seamTR = new Point(60,0)
paths.seam = new Path()
.move(points.seamTL)
.line(points.seamM)
.line(points.seamTR)
.attr('class', 'fabric')
points.from = new Point(45,-5)
points.to = new Point(15,-5)
points.middle = points.seamM.copy()
macro('sewTogether', {
from: points.from,
to: points.to,
middle: points.middle,
hinge: true,
})
return part
}
```
</Example>
## Configuration
| Property | Default | Type | Description |
|----------------:|----------|---------------------|-------------|
| `id` | `sewtogether` | `string` | The ID of this macro instance |
| `from` | | [Point](/reference/api/point) | One side of what needs to be sewn together |
| `to` | | [Point](/reference/api/point) | The other side of what needs to be sewn together |
| `middle` | null | [Point](/reference/api/point) | The middle point (when ommitted, it will be halfway between `from` and `to`) |
| `prefix` | 'sewtogether' | String | The prefix to be used for creating all the points and paths |
| `hinge ` | `false` | Boolean | Draws the hinge line |
| `force` | `false` | `boolean` | Set this to `true` to display the macro output even when `complete` is `false` |
## Notes
This macro takes the `complete` setting into account and won't output anything when both complete and `force` are `false`.
This macro is aware of the `sa` setting. Normally it draws the
hinge line on the inside of the part (following the counter-clockwise
standard). When the `sa` is provided it draws the hinge line on the
outside, up to the `sa` line.
