Undo, redo & history

Step backward and forward — or jump straight to any earlier point in your editing session with the visual history list.

Open in the interactive manual →

The interactive version has full-text search, a table of contents, and light/dark themes.


3dCMS keeps a running timeline of your edits, and you can move along it freely.

RedoCtrl+Y or Ctrl+Shift+Z

The viewport History HUD has matching ↶ and ↷ buttons, and so does the History menu.

Jump to any point

Click the ● history dot in the viewport HUD to open the History list — every recent step, with timestamps. Click any entry to jump straight there, forward or backward. It's a time machine, not just a one-step-at-a-time undo, so you can scrub back to "before I broke it," look around, and scrub forward again.

Smart batching

Related changes collapse into a single step so undo always does the intuitive thing:

  • A gizmo drag is one step, no matter how far you dragged.
  • A burst of typing in a number field is one step.
  • A whole Assistant edit — even "add 42 cubes" — is one step.
History is per-session The timeline is held in memory while you work; it isn't a saved version history. To keep durable snapshots you can return to later, use Save (named local versions) or Save As (a copy on your account).
