All transformation options are also available at the Object →

Transformations menu. There you will find a list with additional tools

regarding object transformation in Blender.

2.2.1 Duplicating objects

In Blender, you will find that some operations will automatically trigger a

transformation. For instance, if you duplicate an object in your 3D

Viewport, it will also move the copied object to a new location. You can

use the same shortcuts and options from transformations, like constraint

them to a single axis.

First, how to duplicate an object? To create a duplicate of any object,

you can use the SHIFT+D keys with an object selected or use the

Object → Duplicate Objects menu. For instance, you can choose one

or multiple objects and press the SHIFT+D keys. By moving the mouse

cursor, you will start to see the duplicates. Click anywhere in your 3D

Viewport to place your newly created objects.

If you want to create a more ordinated set of copies, you can press a

key corresponding to an axis in your keyboard, right after pressing

SHIFT+D. You can create multiple copies of objects in the X-axis using

the X key right after pressing SHIFT+D (Figure 2.7).
