# Group Utilities & Null Objects
***
***
### Copy/Paste Group
From this module you can Copy all of the parameters from one group, go the next group’s Copy/Paste Group and hit the Paste button to copy over all of the attributes. You can also reset all of the Group’s options by hitting reset.
***
### Create Group Null
This will create a 3D Null Object at the center of the scene. You can use the Null Object to control the group’s position, rotation, orientation, and scale. You can also move the anchor point by moving the Null Object’s anchor point value.
Creating a Group Null will control everything in the entire Group or models in a Group Folder.
### Creating Sperate Group Nulls Per Object
Pull the objects out of the Group Folder to put each object on a separate Group Number. You can move an object in the scene if you want it to be off center from the scene, changing the location of the Group Null in relation to the object.
This will allow you to create a Null object for each object separately. For animating separate objects with a single group check out [Auxiliary Channels](https://video-copilot.gitbook.io/element2/~/revisions/uHQWh9OwnnqBlpJf2X5x/animating-3d-objects/3d-object-groups).

### Generate 3d Position
Generating a 3d Position Null is useful for finding a reference position point to add other layers close to Element 3D objects. This can be used for compositing other assets into a scene, such as adding regular AE 3D text or footage near your object, or compositing other 3D effects into your scene.

## 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://video-copilot.gitbook.io/element2/animating-3d-objects/group-utilities-and-null-objects.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.
