Let's create three cubes
Using shift, select a couple of cubes, the “main” one will be the one highlighted in yellow.
We right-click on it with the mouse and in the menu that appears, select Parent and then Object
Repeat the same for the second cube
We try to move the “main” object and make sure that the others follow it
At the same time, “child” objects can live their own lives
An object can have as many children as it likes, but only one parent.
