Is there a way to manually enter in where the center of gravity is on an assembly (based on X, Y, Z coordinates, possibly)?? I'm using a STP file of a motor and want to manually place to COG since I don't know what the materials are of each part to find out their mass properties. I'm in the process of finding out what the actual COG is from a vendor but want to put this into my model so I can see how it affects the overall COG for the assembly that the motor is attached to. Thanks.
Solved! Go to Solution.
Yes u can do it, for creo do to file>prepare>model properties> mass properties> in the top of the window select geometry and parameter and place you predefined value.

That worked perfectly. Thanks.
Don't forget to mark it as correct for those who follow behind.
One caveat: When running a mass properties analysis, Proe & Creo (I just confirmed this is still true as of Creo 2.0 M030)will still use the computed values instead of the values assigned in this manner. Values used in relations will use the assigned, however.
When running an analysis, make sure you pick 'Assigned' instead of the default 'Computed':
BTW - If you,, like me, think that 'assigned' should be the default if there are alternate values present, go and upvote this idea:
Hey Doug,
Just came through this old post. I think that we made this change in one of later datecodes of Creo02 ... not sure by default or we added onfig option for this though - will check.

This is an old post, but it seems that I never verified this statement and @vzak never came back with more information. I'm running Creo 2 M230, the final build I believe, and it still defaults to computed even if a mass value has been assigned. Perhaps it was done through a config option.
