# `GSGuide.intersections`

*Instance Property*

The outline intersections calculated for the most recently supplied layer.

## Declaration

```swift
var intersections: FTPointArray? { get set }
```

```objc
@property (nonatomic, strong) FTPointArray * intersections;
```

```python
intersections() -> FTPointArray
setIntersections_(intersections: FTPointArray)
```

## Discussion

The points are ordered along the guide and exclude the points delimiting the query. A value of `nil` indicates that no intersection line could be formed for the layer.
