Does anyone have a more extensive steel shape list than my 2009 mech comes with?  It seems very limited with the smaller sizes and various shapes.

I have an autolisp routine that will model approximately 100 or so wbeams. It will also model most channels. In the angle routine you specify leg length and thickness so this covers all angles inch and metric. It is very easy to modify these routines to add more sizes as needed. The wide beam routine was originally written with 8 sizes and has grown to over a hundred. These shapes can also be extruded into 3d objects
