Yes. In the U.K. many architects persist in drawing their buildings at OS grid coordinates relative to the origin of the file in mm because it make importing surveys and OS maps easier. So a building in Scotland would have a translate of something like 10000000000, 700000000000mm it's one of the reasons BIM is mysteriously unreliable in practice because points that should be coincident aren't because of of accumulated errors.
