Center of MASS is a three dimensional coordinate system which uses the center of the object(s) as the reference point. Origin is a user defined field which defaults to 0 for XYZ as the reference point.
Basic Measures
Volume — Total area occupied by faceted solid
Mass — The product of volume times density Surface Area — Total area of faceted solid Surface Mass — The product of area times weighted density Measures based on Angular Velocity (XYZ = 0)
Moment/Product of Inertia — Angular equivalent of mass, expresses resistance of an object to rotational change about a given axis
Radius of Gyration — The ratio of moment of inertia to volume
Principal AXES/Moment — On any object there are three mutually perpendicular axis intersecting at the center of mass for which the products of inertia will be 0, grouped as Principal AXES and the principal moments are calculated about the Principal AXES |
