# Split Zones
A zone is drawn to the required dimension and has the same height as all other Zones drawn over the same Drawing. Sometimes, a Zone needs to be split, or divided into smaller sub-zones for more accurate modeling.
## Split a Zone
To split a zone into two, first navigate to the 'Split Zones' symbol and select the zone you want to divide. Hold down 'Shift' to add a new point to the zone, or if points have been previously added during zone editing, you can use those. Next, left-click to select the first point where you want to initiate the split, then choose the second point.
Note that the original zone name will be retained in the split zone, so it's advisable to update the name of the newly created zone for clarity.

## 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/drawing/split-zones.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.
