Determining CG of an assembly in Pro/E

[MikeHeater]

I'm trying to find the CG of an assembly I built in Pro/E. I manually assigned a volume and mass to each of the assembly components using the edit>setup>mass props function. But when I try calculating the CG of the assembly (using Analysis>Model>Mass Properties) I get a CG that doesn't seem correct. Also the mass that is listed in the "Mass Properties" window is off by a factor of 10. I checked and the "Assigned" field is selected so shouldn't it be adding up the mass up all the individual components to find the total mass of the assembly? Any suggestions?

Check that you are using the correct CSO as the origin.

Pro E gives mass in tonnes per mm^3.

Check it again...

Also double check the components and make sure that the density is set to the correct value for the units it is set to. ie not using a metric density value in an english part.
