All changes of layers are traced. Users can use this command to undo changes by "Layer" control or Layer Properties Manager. The LAYERP command can not undo some changes as the following: - Layers renamed: If the layer name and its properties are changed, the LAYERP command can restore the original layer properties rather than the original name. - Layers deleted: If the layer has been deleted or cleared up, the LAYERP command can not restore it. - Layers added: If users add a new layer to a drawing, the LAYERP command can not remove it.
