First, I started by sketching the line on the bottom and making it as long as I want and made the center line under it and made it infinite and smart dimensioned it to 30 degree angle. Next, I made another smaller line measuring 13mm and then measured the whole thing to 84mm. Then, I made a straight lineup and made a big circle measuring 84 for the radius and made a line straight up on the left side in order for it to connect. Then, I made the two smaller circles which the bigger one is 42 for the radius and the smaller to 53mm and trimmed everything on the right side so there's nothing. Next, I made the centerline box on the bottom right side of the sketch and made a centerline at the top left of the smaller circle. Then, I smart dimensioned everything and made sure it matched with the blueprint. Next, I extruded the big piece to 300mm, the half circle part to 225mm and the piece that sticks out to 340mm. Then, I made the bottom lines to 200mm and made sure it was 5mm up from the extruded portion and extrude cut it to 15mm. Then, I at the top of the design, I made a centerline of the 100mm then another line of 35mm and straight down to make a box and extrude cut it to 15mm as well . Lastly, I changed the material and made sure everything was done and checked my mass of the design.
