ASME Y14.3
8.2.2 Identifying Sections
NOTE.
In large [multi-zone/multi-sheet] drawings, themes and variations arise.
Example 1.
A NOTE/footnote can be added to the Lettered Sections/Views/Details [on the main view C/O] to indicate where to
FIND the actual Section/View/Detail, such as...
A^____^A(B4)
B^____^B(Sheet 4/C3-to-D4)
C^(A5)
Example 2.
IF dozens of Sections/Views/Details [on the main view C/O] are anticipated, then this simple letter-scheme can turn into a book keeping nightmare.
One company called out all Sections/Views/Details [on a single main view C/O] with this scheme. But for added Sections/Views/Details initial Section/View/Detail there would be an added number [ascending] for each, thus...
A1^____^A1(x), A2^____^A2

, A3^____^A3(z)... etc
A1^____^A1(x), B2^____^B2

, B3^____^B3(z)... etc
C1^ (x), C2^

, C3^ (z)... etc
Etc...
