202 Chapter 2 Creating and Managing Projects
Nesting Layers Inside Other Layers
In addition to nesting objects inside layers, you can also nest layers inside other layers.
You might do this if you’re creating an object hierarchy to control the relationship of
one group of objects to another, or if you’re grouping layers to which you want to
apply a single set of behaviors and filters.
Nesting a layer works the same as nesting an object.
To move a layer inside another layer:
1 Select one or more layers.
2 Do one of the following:
• Drag the selected layers onto another layer.
• Drag the selected layers to a new position underneath another layer.
• Select one or more layers, choose Edit > Cut (or press Command+X), then select the
layer you want to paste it into, and choose Edit > Paste (or press Command+V).
Grouping and Ungrouping Objects
You can also nest objects together within a new layer using the Group command. You
can group objects that appear within the same layer, or you can group layers that are
all nested at the same level relative to the hierarchy of your project. You cannot group
layers that appear at different levels.
To group selected objects together, nesting them in a new layer:
1 Select all the objects or layers that you want to group together.
2 Choose Object > Group (or press Shift+Command+G).
A new layer is created, which is numbered incrementally based on the number of layers
you’ve created so far. The objects or layers you selected are nested within it.
Groups of nested objects or layers can also be ungrouped, which deletes the
containing layer and moves all objects and layers within it up the layer hierarchy.
