Center of mass analysis of 3d printed parts/assemblies that uses infills.

So, I've designed some stuff to 3d print. Before printing I'd like to do a center of mass analysis. What's the best way of doing so in onshape considering that when printing each part will have different mass distribution as modeled due to infills?

    Assuming there is a constant wall thickness and then the infill, make a copy of the body (transform copy in place), shell one of them, and then use boolean to remove the shell from the fill part. Then assign appropriate densities to the two "materials". This is all assuming that the infill is relatively uniformly distributed.
