Working with Layers

The Layers Panel

The Layers panel helps you organize objects in your document. It displays objects as a list. The top-level items in this list can only be layers. Each layer serves as a folder that can store objects and sublayers. In complex designs, you can place related objects into the same layer to keep them together. A simple design can have a single layer.

To open the Layers panel, choose Window > Layers from the main menu.

The layers panel

1 - Opacity of a layer or object.

2 - The active layer is marked by a line near the panel's left side.

3 - Visibility option.

4 - Layer's color.

5 - Add a new layer.

6 - Blend mode of a layer or object.

7 - Lock option. You can lock an individual object, or a layer with everything inside it.

8 - Delete the active layer.

Each line in the list relates to one layer or one object (or compound object, or group).

Items in the list have default names. To edit a name, double-click on it. Then press the Enter key to apply a new name.

Active Layer

At any given time, one layer is active. If you add an object, the latter will be placed into the active layer. The currently active layer is indicated by a line on the left side of the Layers panel. Only one layer can be active.

Do not confuse the active and selected layer terms. You can select multiple layers, but only one of them will be active.

To activate a layer, click on its name or icon in the Layers panel. A layer also becomes active when you select any object in it.

Visibility of Layers and Objects

Objects you add to the design are visible by default. To hide an object or layer, deselect a check box near its name.

Hiding a layer is equivalent to hiding all objects in this layer.

Hidden objects do not appear on the canvas, are not visible in the exported or printed graphics. Invisible objects do not interact with other objects, for example, there will be no effect from an applied blend mode or a combine option.

Opacity of Layers and Objects

You can make an object or layer transparent or semi-transparent by changing the value in the top left corner of the panel.

Setting certain level of opacity for a layer gives a result similar to setting the same level of opacity for all objects in this layer.

Locking Layers and Objects

You can lock an object or layer by clicking on its lock icon. A locked item cannot be selected and therefore is protected from editing by mistake.

By locking a layer you lock everything in it.

Notice that guide lines have another way to be locked or unlocked using the View > Guides menu.

Layer's Color

Each layer has a color associated with it. It is used to establish the relation between a layer and items in this layer. Once you select an object on the canvas, its boundary or path has the same color as the layer it belongs to. This color doesn't affect your design.

In the Layers panel, the color of each layer is shown as a vertical color bar to the right from the check box.

To change the color, click on the bar and choose a new color from the popup menu.
