Profile, all over (3D) - question
Profile, all over (3D) - question
(OP)
Is the usage of All Over Profile in the attached drawing legal? The 2009 standard only has figure 8-8 devoted to All Over Profile. The wording in section 8.3.1.6 reads to me that the attached drawing is not in agreement with the standard. I am trying to use the all over profile tolerance for only the indentation in the disc and not for the entire part. Legit use of All Over or not?
Thank you.
Thank you.

- "All over" doesn't have to cover the entire part.
- The indentation itself can be broken into several smaller features, so identify every one of them separately would be difficult.
- You clearly indicate where "all over" ends, leaving no place for misinterpretation.
Still, just my opinion"For every expert there is an equal and opposite expert"

It's also a little rough on the inspector that not all surfaces of the notch are identified with basic dimensions, so it's a bit of a trick determining which areas are out of tolerance and which are OK because they are radii.

When it comes to what committee forgot to define - I won't even come close to that.

I do agree, however, with 3D Dave that all surfaces of the notch, including radii currently defined as MAX, should be defined with basic dimensions.
