I've just about finished some computer mouse parts that were created in meters, i.e. the length of the mouse is 110 meters long, not 110 millimeters long. The part data was originally taken from a 3d scanner which for some reason imported it in meters, however now the part is complete Solidworks won't allow me to scale down as the parts go clear with only a few surfaces shown. This design is to be 3d printed so it clearly needs to be re-scaled. Basically I just need to change the part from meters to millimeters, any ideas?

Thanks
