# Sandbox.Rigidbody.InertiaTensor

```csharp
Vector3 InertiaTensor { get; set; }
```

Gets or sets the inertia tensor for this body.
By default, the inertia tensor is automatically calculated from the shapes attached to the body.
Setting this property overrides the automatically calculated inertia tensor until [Sandbox.Rigidbody.ResetInertiaTensor](/api/Sandbox.Rigidbody/ResetInertiaTensor) is called.

Declared in [Sandbox.Rigidbody](/api/Sandbox.Rigidbody).
Assembly: `Sandbox.Engine`.
