# Manage Levels
Levels represent the floors of your building, with each level corresponding to one floor. You can create as many levels as your project requires, there’s no limit. Levels are essential for organising drawings, daylight grids, roof geometry and shading elements across the building.
## Add Levels
To add a level, click ‘Levels’ on the left side, then select ‘+ Add’. Enter the number of levels your building has. Each level can be given a unique title and assigned a specific drawing. Once set, click ‘Add’, then ‘Select Drawing’ to choose the relevant drawing and assign it a title.
## Duplicate Levels
To duplicate a level, hover over any level in the list and click ‘Duplicate’. A copy will appear just above the level you duplicated, allowing for quick replication of similar layouts.
## Edit Levels
To edit a level, hover over the level you want to change and select ‘Edit’. Make your updates, then click ‘Update’ to save your changes.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.betterbuilding.io/user-guide/2d-building/building/levels/manage-levels.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
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.
