# `GSPath applySolutions:toNodes:grid:`

*Type Method*

Applies converted quadratic segments to existing nodes.

## Declaration

```swift
class func applySolutions(_ segments: [GSPathSegment], to nodes: [GSNode], grid: GSGridSettings) -> Bool
```

```objc
+ (BOOL) applySolutions:(NSArray<GSPathSegment *> *) segments toNodes:(NSArray<GSNode *> *) nodes grid:(GSGridSettings) grid;
```

```python
applySolutions_toNodes_grid_(segments: list[GSPathSegment], nodes: list[GSNode], grid: GSGridSettings) -> bool
```

## Return Value

Whether the converted segments were applied.

## Discussion

The segments and nodes must describe the same path segments in the same order.
