calculate the moment of inertia for assembly

Hi all,

I want to calculate the moment of inertia of my assembly roller and I am little confused by the Mass Property function in SW.

As we can see from the picture attached, I want to get the moment of inertia along the X axis, so the  Lxx is what I want, am I right?

And the density if set as default, not the material I want, so I need to multiply the Lxx with a constant to get the right value I want?

Thank you very much!
