moments of inertia

[Matt-Dimon]

I am trying to calculate the moments of inertia on the face of a part is there any way this can be achived in inventor in cm4?

Extrude the cross section a very small amount (0.001") Take the mass moment
of inertia (from the properties) and dive this by the density then divide by
the thickness you extruded. This will give you the area moment of inertia.

I/rho/l = (lbs-in^2) / (lb/in^3) / (in) = in^4
