Castle: 3.Tower with Windows

The Construction of a Tower with Windows.

Objects: "box", "plane".
Methods: "declare", "union", "difference", "intersection", "inverse", "bounded_by"

Sectional view of the tower.

The Construction in Details:

About the construction of windows see here.
First the body of the tower is caved out by subtracting cylinders. Then the holes for the windows were subtracted and finally the predefined windows were put in on the same positions.
