Assigned vs Computed mass properties

In Creo generally you can check the mass properties of an assembly or a part using the function Analysis > Mass Properties. See the dedicated help page for Creo 7.0.

If the assembly contains at least one part that has Assigned mass properties, then you will see the radio button 'Computed'/'Assigned'.

In our assemblies sometimes we use components that have Assigned mass properties (e.g. shrinkwaps), because of this it is important to select the button 'Assigned' when computing the mass properties for this kind of assemblies.
