There seem to be errors in the HSS-Hollow Structural Section-Column.rfa file (RS4 imperial library).
Some of the 3-1/2x3-1/2 tubes have dimensions of 3.5"x2.5" (they are rectangles, not square). And some of the 3-1/2x2-1/2 have dimensions of 3.5"x3.5" (square when they should be rectangles).
Has this been discussed before and I missed it? Is anyone aware of a fix from Autodesk?
