Exercise #3
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
Start with two boxes
Add a third box
• Box C - Size:(30.00, 26.00, 32.00)
• Box C - Pos:(12.00, 9.00, 14.00)
•Union
Add a third box
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
Add a cylinder
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
Add another cylinder
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
