Reverses the last action. The action can be re-performed using the Redo command.

PocketStatics keeps an unlimited list of undo/redo actions. This allows the user to undo all actions in a given session if needed.

This feature is very useful in recovering from errors and mistakes, and gives the user the freedom to experiment with the model, knowing that all changes can be easily undone.

All actions that are associated with modifying the model such as adding and removing elements, loads and supports, and setting element, node and load properties are undoable and are included in the Undo/Redo history. In short, any action that modifies the model can be undone/redone.

Things that are not included in the Undo history include changes in Options and in the current view (Zooming and Panning).

The Undo and Redo actions can also available through buttons on the main toolbar.

Shortcut: Ctrl + Z
