# `GSPath cleanUpGrid:`

*Instance Method*

Removes redundant nodes and rounds node positions to a grid.

## Declaration

```swift
func cleanUpGrid(_ grid: GSGridSettings)
```

```objc
- (void) cleanUpGrid:(GSGridSettings) grid;
```

```python
cleanUpGrid_(grid: GSGridSettings)
```

## Discussion

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