Computes mass properties for the current model using densities of materials assigned to its components.
The density values used for the mass property calculations are taken from materials defined by the Material property of the components and subcomponents, which can be either inherited from the main component of the assembly or set explicitly. The density of the main component is defined by the materials set in the Material field in the Mechanical Browser dialog. If a material does not have an assigned density, or its density is less or equal to zero, an error message displays, and the mass properties will not be computed. All materials involved in the assembly must have non-zero non-negative densities.
Selects the 3D solids and subcomponents or the entire model and will get a Report in the Prompt History window:

- Aligns the UCS with the principal moment axes.
- Keeps the current UCS.
