# 导航场景

使用鼠标或触摸屏，轻松地在 FormIt 模型中导航和浏览：

* **动态观察**：通过单击鼠标右键并拖动鼠标，或者在支持触控的设备屏幕上滑动。这将使用三维空间中要围绕其环绕相机的光标点。
  * 还可以按住 Shift 键进行平移。
* **放大和缩小**：通过向上和向下滚动鼠标滚轮，或捏放支持触控的设备。这将使用三维空间中要缩放到的点，并会在您接近曲面或其他对象时降低缩放速度。
  * 还可以按住 Ctrl 键以恒定速率进行缩放，而不受对象接近度的影响。
* **平移**：通过单击鼠标中键并拖动鼠标，或者在支持触控的设备上拖动两个手指。

还可以使用画布右侧的浮动导航工具栏，以进入特定视图模式。快捷键在圆括号中加以注释。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://windows.help.formit.autodesk.com/zh-cn/formit-introduction/navigating-the-scene.md?ask=<question>&goal=<endgoal>
```

`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.
