I am trying to figure out a way to change the default density that SolidWorks uses to calculate the mass of parts with no material defined. Our company has a large library with no material assigned. It is unfeasible right now to add material to every part but if I could just change the default density to something remotely close than that would get us down the road a bit. Are there any addins to SolidWorks that could edit property's of parts in mass quantity's?

Thanks
