Undo and Redo

Redo

Undo and Redo

Use the Undo and Redo buttons to undo the last actions you have performed, or to redo an action or actions you have just undone. You can also use the following keyboard shortcuts: Ctrl+Z (undo) and Ctrl+Y (redo).

Using undo/redo

When you perform an action in the sketch area, the Undo button is enabled. Each subsequent action is stored in a stack, so that you can undo multiple actions (in sequence), up to a limit of 50 actions.

When you undo an action in the sketch area, the Redo button is enabled, and you can redo multiple actions in the reverse sequence to how they were ‘undone’ previously.

For example, if you:

1. delete a component,

2. delete a line,

3. rotate an object,

The undo sequence will:

1. rotate the object back to its original orientation,

2. restore the line,

3. restore the component.
