Beam Sizes

I just decided to try one of our projects in inventor that uses beams and channels.  After building the part, I was detailing out the parts and the shop noticed that the copes on the beams are not correct.  After measuring the beams in inventor, I notice that the web and flange thicknesses on one of the main beams is pretty far off.  Is this common.


example.  AISC shows a W12x72 web as 7/16" inventor has .55"  the flange as 11/16", inventor has .9" these are both off way too much. Height shows 12 1/4" and inventor has 12.710  This is not going to work if all the beams are off this much.




 Oh sorry, I forgot, this is using Inventor 2013.

My copy is generating exactly as it should.  ANSI W12x72.  Are you inserting this exact one?

This is strange, I just inserted a new one and it comes up okay. 


I attached a pdf of both, notice they both say W12 x72


Not sure what is going on with this.
