First, I started by sketching the front plane with 300mm line on the bottom and on the left side, a horizontal line 50mm up. Then made a centerline 120mm from the left bottom point in order to make the centerline for the circle. Then, I went over to the right side and made a diagonal line 45mm long and made sure it had an angle of 150 degrees. Then, I made a horizontal line up and made another diagonal line and measured the angle to make it 30 degrees. Then, I made a perimeter circle and made a big circle to 280 for the radius. Then, I made the circle in the middle 45mm big. Then, I extruded it to 200mm and changed my material to Cobalt and checked my mass. Onto part 2, I started by sketching out the top part and starting on the top, I made the first line 12.5mm long and made a horizontal line 75 to the right and made a vertical line down 25mm. then I made another line 150mm long and 125mm down and just copied it to the other side. Then, I started tracing the outline and made a centerline of 50mm shown on the blueprint and made a diagonal line downwards at a 45 degree angle and connected the 2. Next, I cut extrude the corners and inside and made a circle in the back to 20mm, cut extrude it and checked my mass. Finally, part 3, I started by using the shell tool, I checked the front, circle and side views as one of the faces to 2.50mm and moved to the pink face and clicked the big wall and the one behind it and changed it to 72.50mm and checked the mass.
