# `GSPath cleanUp`

*Instance Method*

Removes redundant nodes and rounds node positions to the layer grid.

## Declaration

```swift
func cleanUp()
```

```objc
- (void) cleanUp;
```

```python
cleanUp()
```

## Discussion

Cleanup removes nodes that do not affect the path shape within the cleanup tolerance. It also closes an open path when its endpoints are nearly coincident.
