This tutorial is an exercise in which you can apply your understanding of GameObjects and transforms to build a structure out of 3D primitives. In this tutorial, you will:
Add primitives to an empty scene.
Create an empty GameObject as a parent for other GameObjects.
Duplicate GameObjects.
Link GameObjects in parent-child relationships using the Hierarchy window.
Navigate around the scene in the 3D space.
Transform the primitives to a given position, rotation, and scale.
