Drawing abbreviation

Drawing abbreviation

Drawing abbreviation

(OP)
I've run across an abbreviation on a drawing that I've never seen before.  The drawing is an older drawing of structural steel.  A dimension followed by "A.F" is next to the face of a bracket that is welded to the structure leg.  What does the "A.F." mean?  I cannot find reference to it in any drafting book, nor has my drafter heard of it.  Also, is there a book or document that summarizes typical drafting terminology?  

RE: Drawing abbreviation

There is old MIL STD 12 which lists most abbreviations, but I would guess this is After Finishing or such.

RE: Drawing abbreviation

Above Floor?

RE: Drawing abbreviation

http://academics.triton.edu/faculty/fheitzman/abbrev.html shows Above Floor as MintJulep suggests, although Ive usually seen that as AFL (Above Floor Level).

Other suggestions;
Across Flats
Across Flanges
After Finish(ing)
After Fettling (If it's a really old drawing and/or drawn by a really old draughtsman) smile
