How to measure Profile of a surface accurately?

Good afternoon. I'm learning and I need some help. What would be the best way to call out a profile of a surface? Thanks in advance!

  • A bunch of vector points, at multiple levels (different Z depths or different radial intervals), create a set, then dimension the profile.

    That is the general instructions, but now comes the fun part:

    - Is is called against a Datum structure? For example, 0.1 | A | B | C |
    - Is your print in ASME or ISO?
    - Are you measuring against a CAD model? If not, you need to make sure all your nominals and vectors are cleaned up to match the print specifications.

    Those are a few quick questions...
