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?
What technique are you using to rotate with the datum C slot? You want to try this Take multiple points along the slot length, top and bottom of slot. Use those points with a best fit ROTATE ONLY method. Then remeasure the slot for position and width.
That would work, I apologize for not reading that part. It would be simpler to just create a Mid line and do the Rotation to it, Same result.
