I have this assembly made up of over a hundred parts and sub assemblies. I am trying to make a table of all of the components weights, C.G.'s, and Moments of inertia in terms of the over all assembly's origin and orientation, however there seems to be no easy way of doing it in the column properties. I can get the CG's and Moments of Inertia in terms of the individual parts, and I've tried to use the Parrallel axis theorem to get the moments of inertia and CG's in terms of the assembly, but its a real pain in the ass to get the X,Y,&Z axis right. So I am trying to figure out if anyone has come across this issue before and how they solved this problem. I have no experience writing Macros so I am trying to make sure there is no easy way to do this without a macro first before I tackle that project.

Any help you can offer would be greatly appreciated.

You can do this using custom properties:

Insert the properties in your BOM as usual.
