# curve(to:controlPoint1:controlPoint2:)

Adds a Bezier cubic curve to the path.

## Declaration

```swift
func curve(to endPoint: NSPoint, controlPoint1: NSPoint, controlPoint2: NSPoint)
```

## Parameters

- `endPoint`: The destination point of the curve segment, specified in the current coordinate system
- `controlPoint1`: The point that determines the shape of the curve near the current point.
- `controlPoint2`: The point that determines the shape of the curve near the destination point.

## Discussion

Discussion You must set the path’s current point (using the move(to:) method or through the creation of a preceding line or curve segment) before you invoke this method. If the path is empty, this method raises an genericException exception.
