The long leg is d and the short leg b in the AISC database; both legs have the same thickness t.\n- The thickness is taken from the designation (the database prints it rounded to two decimals). The root fillet is not printed: it is derived from the printed k (back of the leg to the toe of the fillet), r = k - t. The toe radius is not printed either, so toes are square.\n- The files put the heel at the origin: the long leg runs along +y, the short leg along +z. 4 in (101.6 mm) long. Drawn area is within 4 % of the printed area on all of them.\n- 31 of the 137 sizes (equal and unequal) have files; all sizes are in the table.\n\nshape  lb/ft  long leg (in)  short leg (in)  t (in)
