TIG, i'm saying isn't it better to have this situation?
@on Layer0, everybody draws their model in SU, say a forrest of cubes.
@now i want to import a dxf, in order to have some drawings that other made, to construct some more geometry into my scene. so it is better to have all the geometry for dxf on other layers that Layer0, to not mess up the entire scene.
all i say is this: the imported dxf should be on it's separate layers, and geometry that is already in SU, should remain on it's layers. Not messing around. Everybody with it's place.
i think this is the best way on keeping everything organised.
cheers!
