# Update Hangers
### Update Hangers
There are 3 different **update commands** in the MEP Hanger ribbon. The most recently used one will always appear at the top and others can be accessed through a drop-down.
Update commands work on both **native Revit MEP elements** (Ducts, Pipes, Cable Trays, Conduits) and **MEP Fabrication Parts**.
To update hangers or supports in your project, select the MEP elements and hit one of the update commands. All hangers and supports on the selected elements will be updated. MEP elements of different categories can be updated at once.
### Update Size
This command updates **sizes**, **rod lengths** (or **unistrut lengths**, if itʼs a unistrut frame support), **# and ## parameter values** of inserted hangers and supports. This update command is different from the others because it wonʼt move the inserted hangers or supports back to their original position if they were manually moved.
For the '**Update Size**' command to work, hangers must stay under (or next to, if itʼs a wall hanger) the same structure that they originally connected to.
### Update Elements
Updates **sizes**, **rod lengths** (or **unistrut lengths**, if itʼs a unistrut frame support), **# and ## parameter values** of inserted hangers and supports, and **moves them according to the Spacing settings** of the applied configuration. If individual changes to the applied configuration were made using the 'Modify' command, 'Update Elements' will work according to these changes.
### Original Config
Updates **sizes**, **rod lengths** (or **unistrut lengths**, if itʼs a unistrut frame support), **# and ## parameter values** of inserted hangers and supports and **moves them according to the current settings** of the relevant configurations (ignoring changes made with the 'Modify' command).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.besmart.software/3d-modeling-and-design/mep-hangers/commands/update-hangers.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
