# init(constrainedToAxis:minimumAngleDelta:)

Creates a rotation gesture with a minimum delta for the gesture to start and axis to constrain measurement of rotation.

## Declaration

```swift
nonisolated init(constrainedToAxis: RotationAxis3D? = nil, minimumAngleDelta: Angle = .degrees(1))
```

## Parameters

- `constrainedToAxis`: The 3D axis about which rotation is measured.
- `minimumAngleDelta`: The minimum delta required before the gesture starts. The default value is a one-degree angle.

## Discussion

Discussion If the constrained axis is nil, the gesture measures unconstrained 3D rotation.
