# Placing Hangers On Linked MEP Elements

By default, MEP Hangers can place supports only on MEP elements in the active model.
\
However, it is possible to place supports on MEP elements from linked models using the **Enable Linked MEP** toggle in the ribbon.

Here's a quick preview:

The **Enable Linked MEP** button has two states:

* A grey lightbulb icon with no highlight around the button indicates it is disabled.
* A highlighted button with a yellow lightbulb icon indicates it is enabled.

To switch between enabled and disabled states, simply click the button.

When **Enable Linked MEP** is active, the **Insert**, **Update**, and **Delete** commands can be used with MEP elements from linked models.

To place supports on linked MEP elements:

1. Select a command (**Insert**, **Update**, or **Delete**).
2. You will be prompted to select elements — at this point, **you can only select linked MEP elements** (Pipes, Ducts, Cable Trays, Conduits, MEP Fabrication Pipework, MEP Fabrication Ductwork).
3. Once finished, click **Finish** in the top left of the screen.

4. **Select a configuration and run it**. This will apply the configuration to the selected linked MEP elements and place hangers/supports.

The **same process applies** when running **update** or **delete** operations: select the command first, then select the elements, and click Finish.

Even when **Enable Linked MEP** is enabled, it is still possible to work with MEP elements from the active model. To do this, select the elements first, then choose the Insert, Update, or Delete command.
{% endhint %}

***

If your configuration uses a filter for MEP elements (to specify which elements to place supports on — [**read more here**](/3d-modeling-and-design/mep-hangers/configurations/hanger-configurations.md#mep-element)), the software will retrieve project parameters from linked MEP elements, so you can use those in your filters as well.

When **Enable Linked MEP** is disabled, all commands (**Insert, Update, Delete, Modify**) will work only with MEP elements in the **active model**.
