Do you mean something like r.to.rast3elev? http://grass.osgeo.org/grass64/manuals/html64_user/r.to.rast3elev.html The link you gave only shows how to drape a 2D raster over elevation, it does not show how to assign z-coordinates and create a 3D raster. Maybe the confusion goes away if you could explain what you want to do with the 3D raster.
