title: lineIntersectsCurve()
---

```js
array | false utils.lineIntersectsCurve(
  Point from, 
  Point to, 
  Point start, 
  Point cp1, 
  Point cp2, 
  Point end
)
```

Finds the intersection between a line segment from point `from` to point `to`
and a curve described by points `start`, `cp1`, `cp2, and `end`.
