center of gravity

[proEdj]

Hello,
I am attempting to calculate the center of gravity of a complex (numerous materials) assembly. I understand that once I define the proper material and density of each individual part that pro-e can do this for me, however I would like to check this value by doing the calculation long hand. I would like to snap a coordinate system to the center of gravity of each and every part, then measure the distance from each of these coordinate systems to the global coordinate system. Is there a function to snap a coordinate system to the center of gravity with our first measuring this location then manually placing a coordinate system at the CG? Also, I would like to find where my center of bouyancy is for each and every part...is there a function to find the center of volume? Some of my parts have cavities which in turn places the CB in a different location from the CG. I do know that this is going to be a huge pain, but any advice to achieve a quick yet accurate result would be greatly appreciated.

Cheers,

Dane

Dane,

To attach a Coordinate System to CG of a part, use the Analysis feature. This feature must be the last feature in each part.

If you want only to obtain different CG, volume, mass etc etc during creation of the part, then insert this analysis feature at the specific location.

Good luck

ProEdj,

To my knowledge Pro/E can't calculate center of bouyancy. Why would you want to go the pain of calculating the Cg by hand.

Best Regards,

Heckler
