Well, you're both wrong... or maybe it's just that you've been using the
cheap set of AutoCad tools. AutoCad will do a large number of design
calculations including area, volume, centers of mass, and moments of
inertia. It will also extract a bill of materials

Oh **** off Doug..... nothing stated was in any way wrong! If you need to
elevate yourself due to some inferiority complex... which seems to be the
case... so be it... but do try to come up with a better methodology than
stating we are wrong and then substantiating what we just said.
