Right-click a virtual component in the browser, and then click Properties.
In the Properties dialog box, enter the component properties.
Note:
A volume and mass can be entered for virtual components. When a virtual component has a volume and mass, the moments of inertia, surface area, and center of gravity of an assembly using virtual components can be inaccurate. Possible reasons are:
The location of virtual component cannot be defined other than the origin of the assembly.
The surface area and moments of inertia of virtual components do not exist.
