ISO default roundness
ISO default roundness
(OP)
I'm tearing up my head discussing DWG's these days.
Q: If a diameter feature in a DWG do not contain a specific roundness tolerance, neither a general tolerance for form. What is the allowable roundness then?
ISO 8015 refers to "The Default Principle", but is there an overall principle for roundness if nothing other than the ISO applies? Anyone?

RE: ISO default roundness
So no, no roundness by default. Specify roundness, specify envelope requirement, specify ISO 2768 - don't complain about lack of options.

I'm not complaining, just arguing with colleagues under-specifying the drawings.
