I want to calculate COG in pro-e for an assembly having say 50 components which will having different densities at different location ,how can i get CG for individual components with respect to one common co ordinate system in assembly.

I want to calculate COG in pro-e for an assembly having say 50 components which will having different densities at different location ,how can i get CG for individual components with respect to one common co ordinate system in assembly. Also i am getting one inter mediate Co ordinate system . Please help me in this case , any body have idea on this.

We do this very frequently and have never had an issue. Our method is define each material for each component on the part level then perform the mass calculation on the assembly level and deselect the use default checkbox and then select the coordinate system you desire. We always define the reference coordinate system on the assembly level though I don't feel it would make a difference. Also it is advised to get this information outside of creo/simulate or pro/mechainca applications.

Hope it works out,

i tried doing all those things but there is some unknown co ordinate system in between from where i am getting the CG values .For example I have same part assembled at three different locations in an assembly, when go for calculating CG through mass properties, I am getting same values of X,Y,Z.
