Undo and Redo an Operation

In the ribbon menu the Undo and Redo is part of the Workbench toolbar (above the home tab).

Alternatively use the keyboard shortcuts:

• Ctrl + Z to undo
• Ctrl + Y to redo

Note: When you delete objects by emptying the Recycle bin (accessed by right-clicking on the Recycle bin and selecting Empty Recycle bin), this is a permanent operation which can't be reversed using the Undo command.
