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.intersectsX()
|
|
---
|
|
|
|
The `Path.intersectsX()` method returns the Point object(s) where the path
|
|
intersects with a given X-value.
|
|
|
|
:::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.
