# `GSPath segmentAtNodeIndex:`

*Instance Method*

The segment associated with a node index.

## Declaration

```swift
func segment(atNodeIndex idx: Int) -> GSPathSegment?
```

```objc
- (GSPathSegment *) segmentAtNodeIndex:(NSInteger) idx;
```

```python
segmentAtNodeIndex_(idx: int) -> GSPathSegment
```

## Discussion

Off-curve node indices resolve to the following on-curve node.

Returns `nil` when no segment can be resolved for the index.
