Undo and redo actions performed in Engineering Solutions.

Not all the actions performed in Engineering Solutions can be undone or redone. If an operation does not support undo/redo, the undo/redo functionality will be disabled once the action is completed and any previous undo/redo history recorded will be reset. The undo/redo history will also be reset every time a macro or other tcl application is invoked.
Note: The undo/redo functionality is supported by most Engineering Solutions panels, tools and user interface functionalities.

By default, the number of undo actions is set to 100 and the maximum undo memory (MB) is set to 2500. You can modify both of these settings in the Undo/Redo Settings dialog from the menu bar by clicking Preferences > Undo/Redo..

Undo/redo history may use a large amount of memory. By default, a threshold of 80% of the total memory limit will not be exceeded. Once the memory threshold is exceeded, all older actions will be automatically purged.

  • Undo an action by clicking from the Undo-Redo toolbar, or pressing Ctrl+Z.
  • Redo an action by clicking from the Undo-Redo toolbar, or pressing Ctrl+Y.
Tip: Simultaneous actions can be undone/redone by selecting them from the Undo/Redo drop-down menus on the Undo-Redo toolbar.
