stacked dimensioning standard
stacked dimensioning standard
(OP)
For decades I have used stacked dimension tolerances with the top dimension being the dimension the machinist comes to first. See example from attached text book. Now I have been told that ISO uses the highest dimension at the top always. Is this true? Is ISO diffrent than ANSI?

(a) Limit Dimensioning. The high limit (maximum value is placed above the low limit (minimum value).

"They still use dimensions with arrow heads at each end?"
When are they 'not' dimensioned with arrows at each end?

Was just a joke cuz of my advance years in the trade and not keeping up with the current trends and standards, although I've used and seen ticks, slashes, dots, etc. at the end of dimensions. :)

Per ISO 406 (1987):
The upper deviation or the upper limit of size shall be written in the upper position and the lower deviation or lower limit of size in the lower position, irrespective of whether a hole or a shaft is toleranced.
