Your Sketch 2 is different from the sketch in homework 3-8 this causing your circular boss extrude to be in the wrong position
Your Sketch 2

Sketch in Homework 3-8

Your resulting extrude is 0.75" from the back when it should be 0.8"

    Hi Dan
    
    Looking at the drawing in the book your model 6061 was correct and the homework 3-8 model was incorrect.

      Hi Paul,
      
      Thanks! I was wondering could you help me on this one also. My drawings seem very similiar. The attached file that says Homework 3-9 is supposedly the solutions and my 3-9 attempt is me trying to model it. Also, I was wondering when the CSWA says ansers must be in 1%. does that mean getting a mass of 44 and the answer should be 45 mean it is wrong?
