Castle Exercise

          For my castle model, I used Boolean tool to make a hole in the box (Figure 1). This will add an effect that the four walls will be the boundaries of my castle. In addition to that, the pink box is taller than the green box, it is because I want to make a "hole". If your "cutter" object is smaller than the object to be cut, there is a possibility that some polygons will still be there.

          Duplicating an object is helpful if you want to add an object with the same size like what I did in Figure 2.
