Tank

First, I started by creating 2 center lines. Then, I created the line of how big the tank is which is 435mm. Next, I created the left side of the front drawing. The lines are 217.5 which is half of 435mm. Then, I created the horizontal line on the bottom which is 390mm or A. Afterwards, I created 2 lines in the middle in order to find the degrees or angle of 92.50 and a radius of 45. Then, I created a circle in between the 92.50 angle and made the circle of 90mm. After that, I trimmed the entities that are needed to get that curve look. Then, I revolved my drawing o the other side of it. Next, I started by completing the top of the tank. I made a circle that was 292mm big and another circle of 274mm. Then, I made a center line in the middle of the circle, smart dimensioned it to get the angle of 55 degrees on the right side of the circle. Then, I made 2 center lines that was 20mm vertical and 25mm horizontal and made a circle with a radius of 45 to make the top circle piece and revolved it to make it looked finished. Then, I made sure it wasn't solid in the inside and to be hollow. Afterwards, I created one of the holes on top of the middle circle piece and extrude cut it. Then I did the same thing on the sides and extrude cut it throughout both sides on the top. Then, I moved onto the bottom and extrude cut it to give it that look lie it can stand up. Finally, I changed the material to 1060 Alloy and checked my mass.
