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.
