True position using z axis and angle

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?

I added two pictures if that helps

please help!!

  • Its not an argument, it a fact. If you do not have a -C- Slot, the you could do the BF rotate ONLY, but since you have a specific -C- that locks 2 DOF, you are not allowed to perform a BF any longer


    He is saying to use BF rotate with the opposed elements for the rotation. It's slightly unorthodox, but not wrong. And C is likely not the "slot", rather it is more likely the median of opposed parallel elements. A TP of the 'slot' to A|B|C suggests this.
