I received a drawing of a cylindrical object with a concentric bore. Under the bore specification is the following symbol; 0/00 Ø0.15 [A]. The drawing is Y14.5M-1982 compliant. What does this phrase mean?
That doesn't resemble any symbol as far as I can tell. /o/ would be cylindricity. Maybe it is a missing symbol in the font that comes with that alternative symbol as a replacement?
