Defining a weight for a specific part for analysis....
(OP)
Lets say you have a solidworks part and it's completely solid.
In the real world the part is not solid but complicated; has mechanical parts and space inside, for example a pump and it's motor.
You're not concerned about this now. The SW parts are for layouts and general shop drawings. In the future though the engineers want to do an analysis and are concerned that there would be inaccuraces because of this.
Can you define a weight for the part regardless of the volume, density, etc.
I'm thinking you can do this.

Make a 2D drawing and add a note "Weight: (###)".
Or, as most do, model the part as it is in real world.
My model, do it right the first time.

So, even if you don't manufacture the pumps and motors you should still model the interior parts?

Also, in older versions of SW, CBL's method does not exist... in that case, use Timelord's recommendation. Timelords method along with changing the density of different bodies of a multibody part (I seem to recall this being possible but have not done it) is how you would move the center of mass.
