1. Open the drawing saved in exercise 5.3 or A3D_05_04.DWG .
2. On top of one of the towers, apply the PYRAMID command, the Edge op-
tion, and specifying two side corners with the height 15 .
3. Copy the pyramid to the other tower.
4. Finally, we are going to build a small wall on the top of the largest box.

to 0.2 units, and justify it to the right . Then we specify the points coun-
terclockwise.
