1. When you switch to world coordinates, the direction of the x, y, and z axes of the object is along the world coordinates. **When the object rotates and creates an angle between it and the world coordinates, the direction of the three axes remains unchanged.**&#x20;
2. However, **after switching to the local coordinates, when the object rotates, the direction of the three axes changes according to the rotation angle**.

{% hint style="info" %}
After switching between local coordinates and world coordinates, all models are uniformly set to the local or world coordinate system state.
{% endhint %}

* World Coordinate System: Refers to the absolute coordinate of space. The world space is the outermost space, and the concept of absolute position is similar to the latitude, longitude, and altitude in the real world.
* Local Coordinate System: It is the model's independent coordinate space. Each model or object has its own front, back, left, and right directions, and rotating or moving and scaling the model cannot change its own directions.

# Agent Instructions: 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:

```
GET https://docs.d5render.com/model/how-to-switch-between-an-objects-own-coordinates-and-world-coordinates.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
