i have a drawing that has a triangle with an "s" inside of it located to the left of a parallel datum callout. can someone define this for me?
i guess that would be a "super" dimension.
from superasme-y14.5
seriously, i'm not sure what the symbol means.

triangles are 'usually' used for revisions. could the revision be that high for your drawing?
well, if it is a revision, there should be a revision history block somewhere on the print. and then we all laugh "rev s?!?! rookie."
in the automotive industry, a triangle would mean a "signifcant characteristic" but it does depend upon the customer.
in gd & t using the older standard, it does mean "regardless of feature size" but i don't think that it applies here.
looks like a customer phone call is coming up.
good luck!

the sw symbol for "regardless of feature size" is an 's' in a circle ... if i re
sounds like it might be a revision symbol. as for the "regardless of feature size" s in a circle:
cbl, that is correct.

maybe the drafts'person' (you can never be sure these days), mistook the number 5 for the letter s....
in that case, the revision would be the 5th one.
i see it quite often in other things, but never before in a revision triangle. that's pretty standard.

this is normally the space where people post something insightful.
if the drafter knew about standards, he/she should know that "s" is not used as a rev, for that reason of mistaken as a 5.
