Ansys TurboGrid includes an infinite Undo feature, limited only by the available memory on
the machine and a few other restrictions described below. Select
Edit > Undo from the main menu or click
Undo
on the toolbar to return to the state immediately prior to when the
last Apply action was executed. Select Edit >
Redo from the main menu or click Redo
on the toolbar to reapply changes that were undone. A
Redo command must follow an undo or Redo command.
The undo function has a few limitations:
When a mesh is created, the undo stack is cleared, meaning that the mesh creation process itself, and all commands before it, cannot be undone using the Undo command.
While creating a session file, the undo/redo commands are not available.
Any action that does not affect the state cannot be undone. For example, creating a mesh cannot be undone, nor can saving a topology file because neither of these actions changes the state.
The undo function cannot return to the initial state of a default object. For example, after defining the
Hubobject for the first time, you cannot click Undo to return to the undefined state of theHubobject.Undo also reverses geometry manipulation when the named view icons located at the top of the Viewer window have been used. Rotation, zoom and translation actions performed using the mouse are not affected by selecting Edit > Undo from the main menu or by clicking on the
icon on the toolbar. You can, however, undo some viewer
manipulations. For details, see Viewer Hotkeys.
The redo feature is used to reverse an undo action. Selecting
Edit > Redo from the main menu or clicking
on the icon on the toolbar can be done repeatedly to
reverse as many undo actions as have been applied.
