Undo and Redo: cancel a change
The curved arrows in the toolbar above the plan are Undo and Redo. Undo takes back your last change, one step per tap; Redo puts it back.
Moved the wrong thing, deleted a piece, or flipped the plan by accident? Undo takes it back. It's the curved arrow pointing left in the toolbar above your plan, on a computer and on a phone. Redo, the arrow next to it, puts back what you just undid.
Step by step
- 2
Tap Undo to cancel the last change
Each tap takes back one change: a move, a resize, a deleted item, a new wall, a flip. Keep tapping to go further back. Undo and Redo keep your furniture selection. Select a group, try Arrange → Flip group left to right, tap Undo, and the pieces are still selected, so you can try another option straight away instead of selecting them all again. A piece that the undo removes (for example, undoing the piece you just added) simply drops out of the selection.
One tap of Undo put the sofa back. - 3
Changed your mind? Redo
Redo brings back what you just undid, one step per tap. Once you make a new change after undoing, Redo starts over from there.

Keyboard shortcuts (computer)
- Undo: Ctrl+Z on Windows, ⌘Z on a Mac. - Redo: Ctrl+Y on Windows, ⌘Y on a Mac. The button's tooltip also lists Ctrl+Shift+Z for Redo. If that doesn't work for you, use Ctrl+Y (⌘Y) or the Redo button.

On a phone
Undo and Redo are in the row of icons under the floor picker. If you don't see them, swipe that row sideways.

Just want one thing gone? Delete it
If the change you regret was adding a piece, you don't need to undo everything since. Select the piece and tap Delete at the top of its panel, or the red trash can next to it on the plan. On a computer, the Delete or Backspace key works too. See select, copy, and delete.
Select the piece, then Delete.
Tips
Make a copy before a big change
Undo only reaches back through this session. Before you rework a whole layout, Duplicate the design (or export a backup) so you can always go back to the original. See managing your designs.
Mid-drawing undo
While you're drawing a circuit line or an area, Undo removes the last point you placed first, so you don't lose the rest of the drawing. Drawing outside walls, Undo takes back the last wall (Redo puts it back), and right after you finish, one Undo takes off just the last wall and brings the drawing tool back so you can redraw it. On an interior wall you just drew, Ctrl+Z (⌘Z) works like the Undo button: the wall goes and you carry on from where it started.
Common mistakes
Expecting Undo after reloading
Undo history lives in the open editor. Reloading the page, closing the app, or opening another design clears it. Your design itself is saved; there's just nothing left to undo.
Using Undo to straighten the view
Turning the plan in Plan Settings → Rotation, zooming and panning don't change your design, so Undo skips them. To straighten it, use Reset in that same Rotation tab; to bring the whole plan back into view, use Fit. See rotating the whole plan.
Frequently asked questions
How do I cancel a change I just made?
Tap Undo, the curved arrow pointing left in the toolbar above the plan (or press Ctrl+Z, ⌘Z on a Mac). Tap again to go back another step.
How many steps can I undo?
Up to the last 50 changes, as long as the design stays open. Each floor of a multi-floor design keeps its own undo steps.
Can I undo after I close or reload the design?
No. Undo history is cleared when the page reloads or you open another design. Every change is already saved, so to get back an older version, keep copies with Duplicate or export a backup before big changes.
Undo took back more than I expected. Why?
One Undo takes back only your last action. An action that changed the walls and the furniture together, like Flip or Re-scale on the whole plan, undoes as one step, so the walls and the furniture go back together. Tap Redo to put it back. (Before October 11, one Undo could also take back an earlier, unrelated change; that was fixed. If you still see it, update the app or reload the page.)
Does Undo work for deleted furniture?
Yes. Tap Undo right after deleting and the piece comes back where it was.
Is there a version history?
Not yet. Use Duplicate to keep named versions, like Living room - before and Living room - after.
