```

### Parameters

**** (\[Vector3]\(/engine/6000.5/script-reference/unityengine/vector3)): 

### Returns

| Type                                                              | Description |
| ----------------------------------------------------------------- | ----------- |
| [Vector3](/engine/6000.5/script-reference/unityengine/vector3.md) |             |

### Remarks

Gets the velocity relative to the articulation body at the specified `relativePoint`.

### Examples

```csharp
using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    public ArticulationBody ab;

    void Start()
    {
        ab = GetComponent<ArticulationBody>();
    }

    // Get the velocity of a wheel, specified by its position in local space.
    // This method assumes that the wheel is a child of the ArticulationBody, or that the wheel translates relative to the ArticulationBody.
    Vector3 CalcWheelVelocity(Vector3 localWheelPos)
    {
        return ab.GetRelativePointVelocity(localWheelPos);
    }
}
```
