The Layers toolbar simplifies interaction with the layer system in 3ds Max, allowing you to easily organize the layers in your scene. While most of these operations are available from the Layer Explorer dialog, the Layers toolbar provides convenient shortcuts to several common actions.

The Layers toolbar provides the following controls:
Manage LayersToggles a floating Layer Explorer dialog.

Displays layer names and properties.
Create New LayerAdds a new layer to the scene and automatically adds any currently selected objects to the new layer. The new layer's name is generated automatically ("Layer001", "Layer002", and so on) but can be changed with the Layer Explorer dialog.
Add Selection to Current LayerMoves the scene selection to the current layer.
Select Objects in Current LayerSelects all objects in the current layer.
Set Current Layer to Selection's LayerSets the current layer to the layer that contains the selected object. Available only when a single object is selected.
