Moment of inertia on multiple bodies

[sendithard]

Attached is my file. There are two separate bodies one is stainless one is aluminum. I am just trying to do a simple moment of inertia analysis. I can only see to find MOI on one selected body. If I select 2 or more, the MOI information window doesnt pop up.  I can still find the COG in the analysis tab so it is able to reference 2 bodies with differing materials still.

Thanks.

Hi,

Thanks, I see you implemented them into a component. I was trying to select both bodies. Your solution is perfect, thanks.

I also tried the same thing with the design uploaded but the density changes.

For body 1 the density is 0.008 and for body 2 the density is 0.003 but the density of the component is 0.004g/mm3

The mass is 858g which is the mass of two bodies combined.
