 Throughout the process, the buffer content itself is not altered — nothing
is deleted. This enables you to restore the changes with the Redo command.
Use Undo to move backwards through the undo buffer (i.e. the changes) and
Redo to advance through the buffer.
 Although nothing is deleted from the buffer, the buffer’s size must be
prevented from taking up too much memory. This is the purpose of Undo
Depth in the preferences — it species the maximum number of actions that
can be undone.
Undo, Undo View
Undo View affects the editor camera only. It has no effect on your own camera
objects.
Undoes the last change, restoring the scene to its previous state. For example, if you accidentally move
an object, choose Undo to restore the object to its correct position. Choose Undo repeatedly to undo
the previous changes one by one. By default, you can undo a maximum of 10 changes. The maximum
number of changes that can be undone is dened by Undo Depth in the preferences (Document page).
Note that the Undo command from the menu of a viewport undoes changes to the editor camera.
You can undo a maximum of 500 editor camera changes.
Redo, Redo View
Redo View affects the editor camera only. It has no effect on your own camera
objects.
Redo redoes a change. Select Redo repeatedly to continue restoring the changes. You can traverse the
recent development stages of your scene by using Undo to move backwards and Redo to move forwards.
Naturally, the number of steps you can redo cannot be greater than the number of actions you have undone.
Therefore, there is no separate setting for the redo depth in the preferences. In a viewport, Redo View
redoes changes to the editor camera only. You can redo a maximum of 500 editor camera changes.
