title: Path.insop()
---

The `Path.insop()` method injects a Path into the [`noop`
operation](/reference/api/path/noop) with id `id`.

## Signature

```js
Path path.insop(string id, Path path)
```

:::tipThis method is chainable as it returns the `Path` object:::


<Example caption="Example of the Path.insop() method">
```js
({ Point, points, Path, paths, part }) => {

  points.left = new Point(10,10)
  points.dartLeft = new Point(40, 10)
  points.dartTip = new Point(50, 50)
  points.dartRight = new Point(60, 10)
  points.right = new Point(90, 10)

  paths.withoutDart = new Path()
    .move(points.left)
    .line(points.dartLeft)
    .noop('dart')
    .line(points.right)

  paths.withDart = paths.withoutDart
    .clone()
    .insop(
      'dart',
      new Path()
        .line(points.dartTip)
        .line(points.dartRight)
    )
    .attr('style', 'stroke-width: 2px; stroke-opacity: 0.5; stroke: orange;')

  return part
}
```
</Example>

## Notes

This is often used to insert darts into a path.
