I am measuring this part right now this is a cylinder about 3 inches tall. The od is dat-b. The top plane is dat-a and dat-c is a slot in the center of the part. The part has 4 counter bore holes along the side of it every 90 degrees. Here is a picture of what the result looks like, and i know its wrong.
Do i need the od dat to be a cylinder or a circle?
Does it matter if its a constructed cyl or an auto cyl?
My dat c is a constructed width, should it be the line instead?
Level to -A- whatever it happens to be. You can and will get drasticly different #'s by using different features as you primary Datum. The only time you will not see any different results is when you create a program Offline from a correct cad model. Brushing up on some GD&T may help you out.
