Either - initializes the global properties retained by this framework from those retained by the framework Item, or - brings together the global properties still retained by this framework with those retained by the framework Item. The value Density, which is 1.0 by default, is used as the density of the system analysed by Item. Sometimes the density will have already been given at the time of construction of the framework Item. This may be the case for example, if Item is a GProp_PGProps framework built to compute the global properties of a set of points ; or another GProp_GProps object which already retains composite global properties. In these cases the real density was perhaps already taken into account at the time of construction of Item. Note that this is not checked: if the density of parts of the system is taken into account two or more times, results of the computation will be false. Notes : - The point relative to which the inertia of Item is computed (i.e. the reference point of Item) may be different from the reference point in this framework. Huygens' theorem is applied automatically to transfer inertia values to the reference point in this framework. - The function Add is used once per component of the system. After that, you use the interrogation functions available to access values computed for the system. - The system whose global properties are already brought together by this framework is referred to as the current system.
