I am studying this leason and the exercise portion of it is missing some critical dimensions. Mainly the size of the pockets,and location of at least the center of it. Maybe i am missing something. Any help would be very much appreciated! Than You

I follow the instructions to the letter and all I get is the big red X on the operation. I can setup the first op no problem, thats the optiarea op. The second op optirest, will no generate at all. II have gone through and changed values restored defaults, everything i can think of but no luck. Anyone else have this problem or know of a solution?
