If I perform the command: File > prepare > model properties > mass properties. The below density displays correctly per below which is an average of the all the components.
But if I perform Analysis > Mass Properties ->>>>>>>>>>>> 
All assemblies display density of 1.000000 which is greyed out, why does not display 7.835694e-06 per top screenshot?
Then you if click the eye glasses, the avg density and mass is correct.
Why is it showing 1.000000 ?

I don't remember looking at this previously but is this just the way it reports the density on an assembly? The "assy" itself doesn't have a density, it has an average density that is derived from its parts. When I calculate the mass props, it gives me the correct number.
