# automaticInertiaTensor

> Whether or not to calculate the inertia tensor automatically.

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/6000.7/script-reference/unityengine.md)
* **Assembly:** UnityEngine.PhysicsModule

```csharp
public bool automaticInertiaTensor { get; set; }
```

### Remarks

If enabled, the inertia tensor is calculated automatically based on the settings of attached [Collider](/engine/6000.7/script-reference/unityengine/collider.md)s. If no colliders are present, the tensor has a default value of Vector3(1,1,1).
