# Edit Grid Settings

Grid setting controls the resolution of the simulation grid in your model. It defines how detailed the grid is, affecting both accuracy and performance.

## Set Grid Size

You can set the grid size in the lower ribbon of the drawing space. Use the dropdown to choose your preferred size, by default, it's set to 0.10 m, but you can adjust it to 0.50 m for quicker modelling or 0.01 m (advanced) for high-detail work.

We recommend keeping snapping turned on for both Zones and Layers to help align geometry accurately. You can toggle these off if needed. Just note, using the 0.01 m grid will slow down modelling significantly and should only be used when that level of precision is essential.

## 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.betterbuilding.io/user-guide/2d-building/drawing/edit-grid-settings.md?ask=<question>&goal=<user_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.
