# Is there a clash detection with linked MEP models?

Use the [**Cut Opening**](https://docs.besmart.software/3d-modeling-and-design/cut-opening) solution, which is part of the **Metal Collection**, to automatically insert openings where walls/ floors/roofs clash with linked MEP models.

1. Find the **Cut Opening** tool in Revit ribbon, in **T4R: Create/Modify** tab
2. Click **Insert Openings**
3. In the dialogue, click on **Find Clashes**
4. Once all clashes are found, click **Insert Openings**

{% hint style="info" %}
You can choose the shape of inserted openings in the [**Cut Opening**](https://docs.besmart.software/3d-modeling-and-design/cut-opening) dialogue.
{% endhint %}

{% hint style="success" %}
Openings can be inserted in Walls, Floors and Roofs
{% endhint %}

5. Use **Frame Wall/Floor/Roof** to create frames or **Update Frame** to adapt the already modeled frames to the MEP.
