title: Path.trim()
---
The `Path.trim()` method Returns a new Path that is this path with overlapping
parts removed.
```js
Path path.trim()
```
<Example caption="Example of the Path.trim() method">
```js
({ Point, points, Path, paths, part }) => {
points.center = new Point(0, 0)
points.base = new Point(0, 10)
points.tip = new Point(0, 50)
points.tipCpRight = new Point(30, 50)
points.tipCpLeft = new Point(-30, 50)
paths.example = new Path().move(points.base)
for (let i = 0; i < 4; i++) {
points["base" + i] = points.base.rotate(60 * i, points.center)
points["tip" + i] = points.tip.rotate(60 * i, points.center)
points["tipCpRight" + i] = points.tipCpRight.rotate(60 * i, points.center)
points["tipCpLeft" + i] = points.tipCpLeft.rotate(60 * i, points.center)
if (i < 2) {
paths.example
.line(points["base" + i])
.curve(points["base" + i], points["tipCpLeft" + i], points["tip" + i])
.curve(
points["tipCpRight" + i],
points["base" + i],
points["base" + i]
)
} else {
paths.example
.line(points["base" + i])
.line(points["tip" + i])
.line(points["tipCpRight" + i])
.line(points["base" + i])
}
}
paths.offset = paths.example
.offset(10)
.setClass("lining dotted stroke-sm")
paths.trimmed = paths.offset
.trim()
.setClass("various stroke-xl")
.attr("style", "stroke-opacity: 0.5")
return part
}
```
</Example>
## Notes
This method is typically used when [Path.offset()](/reference/api/path/offset) caused some overlap.
However, use this sparsely or performance will suffer.
This method is recursive and complex, and the performance penalty for using
it on a long/complex path will be significant.
To limit the impact of path.trim(), follow this approach:
- construct a minimal path that contains the overlap
- trim it
- now join it to the rest of your path
