from the API Help:Is it possible to override the mass properties of an assembly or part
from the API Help:Is it possible to batch-set all the parts of an assembly to one material?
My question is, "Why would one wish to?" The mass is the volume if the Parts multiplied by their density so that (shall we say) "adjusting their mass involves "adjusting" their density. Inertia's derive from the Part's geometry and it's density. If the geometry and density are correct, so are the Inertia values. ???Is it possible to override the mass properties of an assembly or part, as can be done in Solidworks?

Well, I will agree that suppliers of "3D Printing Materials" lie through their teeth about all "properties" they claim (having spent nearly a year-and-a-half performing calibration tests on "3D Printing Materials"). On the other hand, there is "good data" on plastics, laminates, and other "composite" materials. I designed a not-insignificant portion of the Transfer Vehicle" that carried the Curiosity Rover from Earth orbit to the orbit of Mars -- and was accurate on mass within 300 mg and on rotational inertia s to an equal degree.Edit: it's also a good feature when you have non-homogeneous materials, such as some foam and laminated products, and modelling individual layers isn't in your time budget, but weights need to be provided on your technical drawings. Not my use case here, but it was in my previous CAD role.
