Hi Napoleon,


Create a new coordinate system and locate it in the position and angles where you have your reference axis.


Choose "Analysis / Model Mass Properties".


For 'Coordinate System', uncheck 'Use default' and select your newly created coordinate system.


Calculations are now done referenced to you own coordinate system.


Kind regards
Eddy

Thanks Eddy.


I was doing a diferent approch butyour is the more direct one.


I thought that Pro/e had a similar waylike "mechanical desktop" to do this calculation, (just picking up the axis you need)


again, Thanks for your help.

Can you do this in assembly as well ?


I mean, are the results correct in assembly as well ?
