To move a layer in 3D space, you must select the 3D Transform tool or use the 3D onscreen
controls. For more information on moving layers in 3D space, see 3D Transform Tools.
Using Canvas Compositional Aids
When arranging layers in the Canvas, take advantage of various compositional aids to
help you. For example, if you are working on a piece for broadcast or film, turn on the
safe zones in the Canvas to avoid putting layers past the title-safe or action-safe
boundaries. A grid and rulers can also be enabled to provide a useful reference, and
Dynamic Guides can be turned on to help you align layers with more precision.
Furthermore, snapping can be turned on and off to help you position layers relative to
the center and edges of the Canvas, with or without the other guides enabled.
Note: Press Command while you manipulate a layer to temporarily disable snapping,
allowing the layer to move freely.
For more information about enabling various Canvas options to help you lay out your
composition, see Canvas Rulers.
To duplicate a layer
Do one of the following:
µ
Select the layer to duplicate, then Option-drag the layer.
µ
Control-click the layer, then choose Duplicate from the shortcut menu.
A duplicate is created in the Canvas.
Using Object Alignment Commands
The Alignment submenu in the Object menu contains commands that let you reposition
any number of simultaneously selected layers to align with one another in various ways.
These commands make it easy to organize a jumble of layers into an even layout.
After using alignment commands
Before
In each operation, the left, right, top, and bottom of the selected layers are defined by
the bounding box that surrounds each layer. The position of the anchor point is ignored.
