# `GSPath addCurveWithOff1:off2:end:connection:attributes:`

*Instance Method*

Appends a cubic curve segment and aligns its node positions to the layer grid.

## Declaration

```swift
func addCurve(withOff1 off1: NSPoint, off2: NSPoint, end: NSPoint, connection: GSNode.Connection, attributes: [GSShapeKey : Any]? = nil)
```

```objc
- (void) addCurveWithOff1:(NSPoint) off1 off2:(NSPoint) off2 end:(NSPoint) end connection:(GSNodeConnection) connection attributes:(NSDictionary<NSString *,id> *) attributes;
```

```python
addCurveWithOff1_off2_end_connection_attributes_(off1: NSPoint, off2: NSPoint, end: NSPoint, connection: GSNodeConnection, attributes: dict[str, object])
```

## Parameters

- `attributes` — Attributes for the ending on-curve node.
