15. Exercise #3

16. Start with two boxes
• Box A - Size:(7.00, 50.00, 50.00)
• Box A - Pos:(0.00, 0.00, 0.00)
• Box B - Size: (7.00, 26.00, 50.00)
• Box B - Pos:(12.00, 0.00, 7.00)
• Union

17. Start with two boxes

18. Add a third box
• Box C - Size:(30.00, 26.00, 32.00)
• Box C - Pos:(12.00, 9.00, 14.00)
• Union

19. Add a third box

20. Add a cylinder
• Cylinder A - Size: (360.00, 52.00, 4.00)
• Cylinder A - Pos: (25.00, 51.00, 7.00)
• Cylinder A - Rot: (90˚, 1.00, 0.00, 0.00)
• Cut

21. Add a cylinder

22. Add another cylinder
• Cylinder B - Size: (360.00, 50.00, 7.60)
• Cylinder B - Pos: (25.00, 50.00, 27.50)
• Cylinder B - Rot: (90˚, 1.00, 0.00, 0.00)
• Cut

23. Add another cylinder

24. One more cylinder
• Cylinder C - Size: (360.00, 50.00, 7.50)
• Cylinder C - Pos: (25.00, 25.00, -2.00)
• Cylinder C - Rot: (0˚, 1.00, 0.00, 0.00)
• Cut
