Selecting and arranging objects

About layers

When creating complex artwork, it’s a challenge to keep track of all the items in your document window. Small items

get hidden under larger items, and selecting artwork becomes difficult. Layers provide a way to manage all the items

that make up your artwork. Think of layers as clear folders that contain artwork. If you reshuffle the folders, you change

the stacking order of the items in your artwork. You can move items between folders and create subfolders within

folders.

The structure of layers in your document can be as simple or complex as you want it to be. By default, all items are

organized in a single, parent layer. However, you can create new layers and move items into them, or move elements

from one layer to another at any time. The Layers panel provides an easy way to select, hide, lock, and change the

appearance attributes of artwork. You can even create template layers, which you can use to trace artwork, and exchange

layers with Photoshop.

Layers panel overview

You use the Layers panel (Window > Layers) to list, organize, and edit the objects in a document. By default, every new

document contains one layer, and each object you create is listed under that layer. However, you can create new layers

and rearrange items to best suit your needs.

By default, Illustrator assigns a unique color (up to nine colors) to each layer in the Layers panel. The color displays

next to the layer name in the panel. The same color displays in the illustration window in the bounding box, path,

anchor points, and center point of a selected object. You can use this color to quickly locate an object’s corresponding

layer in the Layers panel, and you can change the layer color to suit your needs.

When an item in the Layers panel contains other items, a triangle appears to the left of the item’s name. Click the

triangle to show or hide the contents. If no triangle appears, the item contains no additional items.

A Visibility column B Edit column C Target column D Selection column

The Layers panel provides columns to the left and right of the listings. Click in a column to control the following

characteristics:

Visibility column Indicates whether items in the layers are visible or hidden (blank space), or whether they are

template layers or outline layers.

Edit column Indicates whether items are locked or unlocked. The lock icon indicates that the item is locked and

cannot be edited; a blank space indicates that the item is unlocked and can be edited.

Target column Indicates whether items are targeted for application of effects and edit attributes in the Appearance

panel. When the target button appears as a double ring icon (either

or ), the item is targeted; a single ring icon

indicates that the item is not targeted.
