  See Change the wireframe color of a layer.

• Right-mouse click a layer name to display a menu allowing you to perform actions on that layer without having to select it first (for example Assign, Pick Objects, and so on).

Columns

You can sort the layers based on the values in any of the columns by clicking on the column title. Clicking again sorts in reverse order.

Number

The number of the layer. This is useful when working with external CAD packages that expect certain objects on specific numbered layers.

To display layer numbers instead of names in the Layer Bar, choose Preferences > General Preferences, go to the Modeling section and set Modeling Layers mode to Number.

Visible

Whether the layer is shown in the view windows.

Pick State

The layer’s state: Pickable, Reference, or Inactive.

Symmetry

Whether Alias displays a symmetrical half for the objects on this layer.

See Automatically create symmetrical geometry.

Objects

The type of objects contained in this layer (Curve, Surface, Locator, and so on). Trimmed surfaces and regular surfaces are both referred to as “Surface”. If a layer contains more than one type of objects, then this column displays “Mixed”.

Layer Bar

Whether the layer is shown in the layer bar. Turn this off to remove the layer’s button from the layer bar.

Playback

Whether animation on this layer plays when you click Play on the animation bar.
