Creating object aliases
You can also duplicate an object by creating an alias. In this case, any change to the original object is reflected in the copy. When you make an alias to an object, both objects become aliases to each other. Duplicating objects by creating aliases is particularly useful for speeding up redrawing of objects, minimizing the file size of a composition, and saving time when updating Web pages.
You can modify an alias independently of the original by unlinking the alias from its parent.
To create an alias of an object:
- Select the object for which you want to create an alias.
- Do one of the following:
- Choose Edit > Make Alias.
- Shift+Alt-drag (Windows) or Shift+Option-drag (Mac OS) the object.
Original with alias (left) and after modifying original (right). When the original is modified, the alias is modified automatically.
To unlink an alias:
- Select the alias you want to unlink.
- Choose Edit > Break Alias.
