Undo (Edit Menu)

This command can be used to undo the last operation carried out. It can be used with all commands which create, alter or delete objects, instances or Construction Aid objects. This also includes changes in elements like pens, layers, pages, and variables.

Some operations cannot be undone. These are mainly operations which alter settings or definitions, as well as alterations to blocks and 3D views. These are examples of operations which cannot be undone:

Successive operations can also be undone. The maximum number of undoable operations depends on the "Undo Steps" setting in the command Edit > Options > General.

The undo information needed to undo operations is not saved along with the drawing, i.e. it is lost when the drawing has been saved and is loaded again.
