Undo/Redo 93
Note:
Viewport changes such as panning and
zooming have a separate Undo and Redo. See
View-Handling Commands (page 1–35) .
The Hold and Fetch command pair serves as an
alternative to Undo and Redo. Hold saves the
current state of the scene. After using Hold, you
can restore that state at a later point by using Fetch.
Sometimes, when you are about to perform a risky
operation, an alert prompts you to first use Hold.
3ds Max does not have the Cut or Paste functions
found in many Windows applications. The Delete
command simply removes the selection from the
scene.

The Undo command reverses the last operation
performed on any selected objects. Redo reverses
the last operation performed by the Undo
command.
When you create an object, the Create operation
is recorded by 3ds Max and displayed next to the
activated Undo command in the Edit menu. When
you undo the Create operation, the Redo Create
operation is displayed next to the activated Redo
command in the Edit menu. The Undo and Redo
commands in the Edit menu are unavailable when
no valid operation was performed or recorded.
By default, there are 20 levels of Undo. You can
change the number of levels with the Customize >
Preferences >
General tab (p age 3–859) >Scene
Undo group.
Some actions cannot be undone: for example,
applyingtheCollapseutilityorResetTransform
utility, and saving a file, thus overwriting the
previous version. When you know something
cannot b e undone, use
Hold (page 1–94) first.
Then if you want to undo it, use
Fetch (page 1–95) .
Hold and Fetch are also commands on the
Edit
menu (page 3–721)
.
Undo (page 1–93) and Redo (page 1–94) are
also available as buttons on the main toolbar.
When you r ight-click the Undo or Redo button, a

performed. You can highlight and reverse any
number of these operations in sequence with the
respective Undo or Redo command.
