# sendChildDimensionsChange

> Whether the RectTransform notifies components when a child RectTransform changes dimensions.

## Definition

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

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

### Remarks

If true, this RectTransform calls [MonoBehaviour.OnChildRectTransformDimensionsChange()](/engine/6000.6/script-reference/unityengine/monobehaviour/onchildrecttransformdimensionschange.md) on all components attached to the same GameObject when any of its child RectTransforms change dimensions.
