Why is the density of the assy always show 1.000000

Why is the density of the assy always show 1.000000

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 ->>>>>>>>>>>> Capture2.JPG

  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 ?

Brad,

I was able to reproduce the problem in CR2 M070. Please contact PTC Support and report the problem.

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.

True, it will calculate the correct average density, but strange why it displays 1.00000 and is greyed out.  Seems like should display the average density.  I have logged a call with PTC, waiting for answer.

Maybe Graphic card not support , please buy a new one

PTC replied................."Assembly doesn’t have its own density and will be calculated based on the components assembled."

That is a true statement....So really I am ground zero again, just seems like the greyed out Density field should display the avg and not 1.0000.
