Undo / Redo
Slide2 provides a very handy Undo/Redo functionality, which allows you to easily undo or redo any changes to your model or drawing tools with a single mouse click. Undo and Redo are available in the Edit menu and as toolbar buttons.
- From the Edit menu, only 1 action can be undone/redone at a time.
- From the toolbar, if you select the drop-down arrow beside the Undo or Redo buttons, a list of all changes will appear, from which you can select multiple (sequential) actions to undo or redo.
UNDO
The Undo 
option allows you to undo changes to your model (e.g. adding/editing boundaries, support, loads, material properties, etc) or drawing tools. Any number of changes can be reversed with Undo, starting with the most recent change and progressing backwards.
REDO
The Redo 
option allows you to restore changes that you have undone with the Undo option. Redo will restore each use of the Undo option, starting with the most recent Undo and progressing backwards. Redo is only enabled if at least one Undo action has been performed.
