I can't give you details, but it's a flat, thin piece of float glass that is being die cut to shape. The question was really more theoretical, and could apply to any part though.
So if I want to require them to measure more than one location for width and parallelism, I need to create a note to say so?
Thanks a lot for the quick answers, it helps.
I have a fairly simple callout for the width of a glass sheet (319.173 +/- 0.5 mm, one edge parallel to opposite edge within 0.3 mm). I am wondering if there is a minimum number of locations that the width needs to be measured. Are they required to run a probe down the whole edge and report...
