Mass Properties Tool
Use the Mass Properties 
tool to display volume information for the objects in your
design.
Note: The accuracy of the mass properties calculation is based on displayed
facets, approximations can occur based on faceting.
If you use the tool on a surface, it will display the total surface area. If there are multiple surfaces on the same plane, the tool displays the total surface area for all the surfaces. To display the surfaces' individual surface areas, use the Measure tool.
