# Normal Picker
This operator lets you "pick" normal data from mesh faces or the look direction of the viewport. This normal data is then used by some random operators like **Random Animation**, **Random Cables** when using the **Cable Type: Curve** and **Random Scatter** when **Follow Normal** is turned off.
Figure 1
In Figure 1, the picked normal of the face is used to offset the curves in **Random Cables** using its direction.
Figure 2
You can also pick on the empty space of the 3D viewport to set its "look direction" as the normal data. In Figure 2, this method is used with **Random Animation** to align the animated objects towards the viewport which is done by enabling on the **Add Parent Empty** toggle.
Figure 3
With **Random Scatter**, you use this method by disabling **Follow N**ormal and using the **Track Picked Normal** toggle.
Figure 3
If you pick at the empty space in the 3D viewport, this will show you a message at the bottom saying "Face normal not found. Using view direction instead".

## 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://www.blenderguppy.com/add-ons/random-flow/functions/normal-picker.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.
