A structural engineer asked me to find the center of gravity of a steel truss. But not the center of a mass - I mean the actual center of gravty - taking into account the weight per linear foot of steel of all members involved. Is there a way to do this using Revit Structural or even regular Autocad?

What is the difference between center of mass and center of gravity?

There isn't a difference, unless he's a theoretical physicist working with non-uniform gravitational fields, in which case I don't think he'd be here asking questions. *Penny, Penny, Penny*

That was my point.  It was a trick question or the "engineer" needs to go back to school.
