To show or hide selected layers
Do one of the following:
µ
Click the checkbox to the left of an object or group in the Layers list or Timeline.
Activation checkboxes
µ
Choose Object > Active (or press Control-T) to turn the layers on or off.
µ
Control-click a layer or group, then choose Active from the shortcut menu.
Note: If you hide layers in a group, the enclosing group’s checkbox displays a dash instead
of a checkmark, to indicate that some layers are not visible.
You can “solo” a layer or group to hide all other layers in the project. This technique can
be useful to isolate a single object in the Canvas to animate or manipulate without
interfering with other objects in your composition.
To solo a layer
µ
Select layers or groups to solo.
µ
Choose Object > Solo (or press Control-S).
Note: You can also Control-click an object in the Layers list, then choose Solo from the
shortcut menu.
All other layers or groups are deactivated, and only the soloed object is visible in the
Canvas. When the selected item is soloed, the solo menu item displays a checkmark.
Fixing the Size of a Group
By default, the size of a group is determined by the layers in that group. Because animated
objects often grow in size, the active height and width of a group (its resolution) can
become large. You can constrain the resolution of a group to a specific width and height
in the Group pane of the Inspector.
