WebJul 31, 2024 · I am of opinion for flatness and perpendicular surfaces 0.4 or 0.5 is acceptable range for 1.2M long plate and for round depending upon if its tight fit or sliding 0.05 to 0.2. In a nutshell, I am doing manufacturing detail drawings and need to know acceptable values for flatness, perpendicular, rounds (for sliding and tight finish) to put in ... WebThe perpendicularity callout is not tied to the basic dimensions. You need to locate the hole's position, the perpendicularity callout limits the angle of the axis. You can add tolerance to the linear dimensions, rely on the standard drawing/note tolerance, or add a position callout on the hole. As it is, the hole location is not defined.
