There is an option to create instances of Collections using the

SHIFT+A keys. Locate the Collection Instance option to add an

instance of existing Collections.

As you can see from the list, you have multiple benefits by using

Collections in your projects. For that reason, it is important to not only

use them but assign meaningful names to each of the Collections. That

helps to identify what types of objects they hold.

Tip: You can also use Collections from the Add menu. If you look at the

bottom of the menu, you can create new instances from existing

collections pressing the SHIFT+A key.

2.6.1 Renaming objects

As you start to create objects in Blender, you will notice that their names

appear as a combination of object type and a numeric sequence. The

default Cube displays the name of "Cube," after adding another object of

the same kind, it receives the name of "Cube.001".

Unless you rename those objects, after a few hours of work, you might

have a scene filled with Cubes starting with "001" and going all the way

to "100". That is terrible for scene organization, and you will easily lose

control over the project.

To avoid losing control, keep in mind that each object in Blender must

have a unique name.

To help manage object names, you have multiple ways to quickly identify

the name of any selected object. When you select an object, look at the

top left corner. There you find the active Collection and the name of your

selected object (Figure 2.33).
