the center of mass of my part is correct in the z direction and looks reasonable in the y direction but it is on the wrong side of the assembly, all components are made out of the same material, with the correct density,(the weight is also wrong but i can calculate that based on the volume) any suggestions why this might be the case?
i know i can override the mass properties but i dont know why i should have to.
any help appreciated.
it is a simple rectangular duct with the pipe cut at the intersection of the sheet metal
i would expect the center of mass to be on on the side with the pipe as it is symmetrical apart from the pipe.

Hello
It seems that there are free parts in this assembly, I don't know if that's it but first maybe review the assembly constraints?

Apart from the unfixed parts as seen with @Scofield , don't you have bodies (in one of your rooms) that would just be hidden (instead of removed) and that could modify the center of mass?

thanks for the response, I fully defined it and it made no difference.
thanks, there are no hidden or suppressed bodies
i have just checked the masses of all of the components, the only one that is correct is the sheet that the center of mass is on(25kg) the rest are far too low (3kg) this explains the issue but why are the masses wrong for each part?
edit
i figured it out, I had changed the density of the material after applying them so i needed to update the densities for each part. thanks for the responses
