# Delete elements in a semantic model

Delete elements from a semantic model that you no longer need. 

{% hint style="info" %}
**Notes**: 

* Deleting an element might impact model consistency because elements reference other elements. When you delete an element, the system displays a warning message with a list of elements that might be affected by the deletion.
* To locate an element in a large semantic model, you can click the **Model Structure** tab and then navigate to the element by searching or scrolling through the list.
