Coaxial holes

Jay_Q
I have attached a call out below. What would be the best way to report this out. They are 2 cylinders in line about .250” long each with a 2” space in between. I’ve tried to
1. level and origin on one then report the TP. Of the other
2. 3D best fit both cylinders trans and rotate and report of both cylinders using worst end of axis.
3. using geo-tol by selecting both cylinders with no datum

all of these came up with different results. Which is the best way? Any of these 3 or maybe some different ways?

Should both holes be reported out or just the one? Because technically one becomes datum in way.

  • I do not understand the GD&T.

    "2 coaxial holes"..? "Is there a tolerance? What is to be coaxial to what and within what tolerance range?" would be the questions I'd ask the design authority.

    Also agree with others, dropping the -A- on the lower portion doesn't make sense. TP needs datums.
