How do I set the DENSITY of a solid (say a sphere) such that when I perform a TOOLS=>INQUIRY=>REGIONS/MASS PROPERTIES I get the correct mass of the solid? It always gives the same mass as volume (i.e. density = 1). Example: Mass: 4.1888 Volume: 4.1888 Bounding box: X: -1.0000 -- 1.0000 Y: -1.0000 -- 1.0000 Z: -1.0000 -- 1.0000 Centroid: X: 0.0000 Y: 0.0000 Z: 0.0000 Moments of inertia: X: 1.6755 Y: 1.6755 Z: 1.6755 Products of inertia: XY: 0.0000 YZ: 0.0000 ZX: 0.0000 Radii of gyration: X: 0.6325 Y: 0.6325 Z: 0.6325 Principal moments and X-Y-Z directions about centroid: I: 1.6755 along [1.0000 0.0000 0.0000] J: 1.6755 along [0.0000 1.0000 0.0000] K: 1.6755 along [0.0000 0.0000 1.0000]
