The replaces the NextJS site powering FreeSewing.dev with a Docusaurus setup. It's part of my efforts to simplify FreeSewing's setup so we can focus on our core value proposition.

title: Path.intersects()
|
|
---
|
|
|
|
The `Path.intersects()` method returns the Point object(s) where the path
|
|
intersects with a path you pass it.
|
|
|
|
:::warning
|
|
|
|
This method can sometimes fail to find intersections in some curves
|
|
due to a limitation in an underlying Bézier library.
|
|
Please see [Bug #3367](https://github.com/freesewing/freesewing/issues/3367)
|
|
for more information.

## Notes
|
|
|
|
This is an expensive (read: slow) method that you should only use when you don't know
|
|
in advance in what segment of your path the intersection will occur.
|
|
|
|
If you do know, use one of the intersection methods in [Utils](/reference/api/utils).
