The Quick Access Toolbar, displayed above the ribbon, enables you to quickly use standard functions, such as Save and Undo, without using the ribbon:
Use this option to reverse the last command.
You can click Undo multiple times to reverse multiple commands, back to when you last saved the model.
A set of the last performed commands are remembered for each model opened. You can Undo and Redo commands in one model, then go to another model, and Undo and Redo its commands too.
For dialog operations, Undo reverses the action of a dialog. It does not undo individual operations within the dialog.
When creating Bézier, G2, and Spline curves, Undo undoes individual curve points. You can undo curve points back to the first point created, but when the curve is complete, Undo undoes the whole curve.
