Structural Angle symbol in callouts

Structural Angle symbol in callouts

Structural Angle symbol in callouts

(OP)
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."

RE: Structural Angle symbol in callouts

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)

RE: Structural Angle symbol in callouts

ditto JAE's response.
