   • Use the keyboard shortcut: Ctrl+Z.

Options

• To undo multiple actions click on the small black down arrow to the right of the Std Undo button and select from the list.

Preferences

• The Undo/Redo functionality can be disabled by setting Tools → Edit parameters... → BaseApp → Preferences → Document → UsingUndo to False, but this is not recommended. This setting can also be changed in the Preferences Editor.

Scripting

See also:

FreeCAD Scripting Basics.

To undo the last action use the undo method of the document object.

import FreeCAD

FreeCAD.ActiveDocument.undo()

When running FreeCAD in pure console mode (CLI), the undo/redo mechanism isn't enabled by default. It must be explicitly activated for each document.

import FreeCAD

FreeCAD.ActiveDocument.UndoMode = 1
