Edit Commands
These commands on the Edit menu (page 3–673)
are for basic edit manipulations of selections.
UndoandRedoworkasinstandardWindows
applications. These commands are available on the
default main toolbar as well. 3ds Max also provides
a history of commands. Right-clicking the Undo
or Redo buttons displays a list of commands you
can undo or redo. Not all operations are reversible
using Undo.
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 fro m the
scene.
