Cylindricity and roundness

[JamesMannes]

I have a metal sleeve that goes into a crankcase cylinder before the die is closed and a shot made. This cylinder has cylindricity called out with a tolerance of .002. I created an auto-cylinder and reported the cylindricity(oh and by the way cylindricity is a new icon on the dimension toolbar in 4.0 and above), it measured in tolerance. I created 4 auo-circles, reported out the diameter and circularity, and 3 of the 4 were OOT for circularity. Can anyone tell me what I am seeing? This doesn't sound right to me? Am not thinking this through properly? Here is a snippet...

Is everything equal? I mean are the circle hits and the cylinder cross section hits in the same place? If there was form error thats how the dimensions would look.

[JamesMannes]

No, that was the problem. I was re-doing someone's work and the cylinder was not created the way I would have done it (15 points 5 levels vs. their 5 points and 5 levels). Caught it after I posted. Thanks anyways.
