callouts for sections over z-z
hello - i would like to know what is accepted practice for calling out sections over z-z - is it aa-aa or what - any info would be appreciated - thank you
yes.
take a look at asme y14.3-2003 section 1.7.3. identifying removed views.
quote:
...when the alphabet is exhausted, additional removed views shall be identified by double letters in alphabetical order, as in aa-aa, ab-ab, ac-ac, etc.
kenat,
i have never seen sections go that far.
maybe aab? just a guess..

after az-az would be ba-ba, all the way to zz-zz if you really needed it.
not using i,o,q,s,x,and z that's what, 20 squared or 400 sections before needing aaa,aab,etc?
i've seen some j size aircraft drawings with a ton of sections, but nothing close to using up the double letter limit.
yeh, kenat was taught well
no longer the least qualified checker.

i had at least one good teacher.

kenat,
i think that i've gotten up to around aj-aj before, but that was a rare occurance.

hello again & thank you so much for the replies - we have had so many problems w/ our assembly drawings w/ over seas manufacturing that our v.p. has instructed us to take as many views & sections as possible - this is the very 1st time i myself have run out of letters - once again this forum has become so valuable - thank you again
wow, sorry i'm amazed.
usually managment, or similars, response is to create lots of exploded view or the like. they claim shop floor workers can't understand sections etc.
however 'take as many views & sections as possible ' still sounds odd.
i'm of the 'minimum number of views necessary to fully define the part/assembly' school.
eitherway, glad to be of assistance and good luck.

certainly sounds like a solution to a problem that it not understood.
