Calculating the CG of an assembly in Pro/E

Calculating the CG of an assembly in Pro/E

Calculating the CG of an assembly in Pro/E

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?  

RE: Calculating the CG of an assembly in Pro/E

One or more of your components has an incorrectly assigned density.

Also take care that units of measure for each component is set individually.  Density must agree with the component's unit of measure.
