The Moment of inertia for an AutoCAD region is usually calculated for an
axis at the base of the region if I am not mistaken.

I have a feeling that this might have been posted before.
In AutoCAD under "massprop" the section properties such as area, perimeter,
centroid, Moment of Inertia etc are calculated.
I did a check on a complex section by hand and I found that AutoCAD produces
a different answer from mine for the Moment of Inertia. The other values
appear correct but not "I".
Does anyone know if I did something wrong or what AutoCAD is doing? This is
not my software so the licensee may have set up something in the program??
