Every drawing includes a layer named 0. Layer 0 cannot be deleted or renamed.
It has two purposes:
Ensure that every drawing includes at least one layer
Provide a special layer that relates to controlling colors in blocks
NOTE It is recommended that you create several new layers with which to organize
your drawing rather than create your entire drawing on layer 0.
For information about controlling the display and behavior of the Layer
Properties manager, see
Specify the Behavior of Dockable Windows on page
