# init(named:skeletalJointName:offsetPosition:offsetOrientation:)

Creates a geometric pin that attaches to a skeletal joint.

## Declaration

```swift
init(named name: String, skeletalJointName: String, offsetPosition: SIMD3<Float> = SIMD3<Float>(0, 0, 0), offsetOrientation: simd_quatf = simd_quatf(ix: 0, iy: 0, iz: 0, r: 1))
```

## Parameters

- `name`: Name of the GeometricPin in the namespace of the owning entity.
- `skeletalJointName`: Name of the skeletal joint that this pin attaches to.
- `offsetPosition`: Adjustment of the GeometricPin position in the coordinate frame of the joint.
- `offsetOrientation`: Adjustment of the GeometricPin orientation in the coordinate frame of the joint.

## Discussion

Discussion The current animated joint transform defines the position and orientation of the pin.
