Null Objects
Use a null object to group other objects. A null object doesn't have a shape, but it can be manipulated in 3D space.
Objects grouped under a null object are known as its children. They'll take on the properties of the null object. For example, if you change the scale of a null object, any children will change scale too.

To insert a null object:
- Click Insert.
- Select Null Object from the menu.
Making Changes to Null Objects
When you select a null object in the Scene tab, you'll be able to see and make changes to its properties in the Inspector panel.
