SolidWorks Initial Model

Mass = 2014.69 pounds Volume = 55766.55 cubic inches Surface area = 24514.17 square inches Mass = 913848.011 grams Volume = 9.1385E+8 cubic millimeters Surface area = 1.5816E+7 square millimeters To create this, I first used the circle tool to make the top circles. Then I used the sketch pattern tool to make the circular pattern of holes. After that I used construction lines to place the bottom right circle in the right spot. Then I mirrored it. Finally I created the bottom circle and did the boss extrude.
