# center

> The default orientation of a bone when no muscle action is applied.

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/6000.6/script-reference/unityengine.md)
* **Assembly:** UnityEngine.AnimationModule

```csharp
public Vector3 center { get; set; }
```

### Remarks

The vector value represents the bone's rotation in degrees around the X, Y and Z axes relative to the initial position of the bone in the skeleton. Any muscle rotation subsequently applied to the bone will be relative to this value.

If [HumanLimit.useDefaultValues](/engine/6000.6/script-reference/unityengine/humanlimit/usedefaultvalues.md) is enabled, the value of `center` will be \[0, 0, 0].
