Thanks for the pointer, Makoto. I searched the wrong documentation (where GetMass() isn't even found). The connection to GetCubicVolume() of the solids is obvious once you know about it, and the MC estimation explains the per-mil or so difference I saw with each instance. It all makes perfect sense, and is good enough for my application. Regards, Mike
