When using the Inch standard, is it mandatory to use 3 decimals in the feature frame?
(OP)
I have always seen 3 decimal places in the feature frame when using the inch standard. It seems worthless to include the superfluous zeroes in the dimension, just for the purpose of consistency with the feature frame. For instance, the dimension is .xx, the positional tolerance is .xx. Does correctness require the trailing zeroes in the FCF and/or the dimension?

Per ASME Y14.5-2009 ¶2.3.2(d) "Where basic dimensions are used, associated
tolerances contain the number of decimal places necessary
for control. There is no requirement for the basic
dimension value to be expressed with the same number
of decimal places as the tolerance."
