I'm at a bit of a loss as to what to say. Your model is all loose geometry, the only component is the scale figure that shows as a nested instance. Once Solid inspector has fixed the issues it can there are still holes and overlaps that you need to address manually. To get a volume the object needs to be a solid.

You don't need any special extensions or plugins to do this. Just enter the coordinates in the Measurements window. For relative coordinates use the form <x,y,z> and for absolute coordinates use the form [x,y,z]. I used relative coordinates in this example. And then the Text tool will show the coordinates when the leader is anchored to a point in the model. [image: BdAL_relative.gif]
