Layers

Layers are virtual levels in a drawing, analogous to acetate tabs (overlays) in traditional drafting. Layers enable you to sort objects in your drawing by type, by creation order, or by any criteria that suits the way you work. You can also use layers to protect certain objects from being edited or deleted.

Panel
NOTE: Layers are not related to how objects are stacked in relation to their order of creation. If you change an object's layer, it does not affect its position in the object stack.

You may delete any layer except Layers 0 and $CONSTRUCTION. Layers can be deleted even if they contain objects. If the layer to be deleted is set as the default for a tool (in the General page of a tool's Properties window), you will receive a warning message before the layer is deleted.

...

In some cases, objects on deleted layers will be moved to Layer 0, rather than be deleted. If an object exists on Layer 1 in both Paper Space and Model Space, and Layer 1 is deleted from Model Space, in Paper Space the object will be moved to Layer 0. This is due to different Undo buffers for Model and Paper Spaces.

Layer Templates

Layer templates allow you to create and save alternate configurations for layers. Layer templates store how layers are setup, but do not store layers thenselves. Layer templates are saved in a *.lrs file which can be stored anywher in you system directory.
