structural angle symbol in callouts
when calling out structural angles in an autocad file, what symbols are used in the prefix and/or suffix of the callout in different cases like an single angle with the long leg up or down or a double angle with long legs back to back? the more examples i have the better.
some engineers have seen an angle represented as a reversed "l" before the description(3x3x1/4) but the aisc shows "l 3x3x1/4."
check out our whitepaper library.
i believe aisc recommends the following:
single angle:
l3x3x1/4
double angle:
2 l4x3x1/4 (llbb)
(meaning double angle with long legs back to back)
single angle with long leg vertical:
l4x3x1/4 (llv)
ditto jae's response.

lutfi
