# Sandbox.Helpers.UndoSystem.Snapshot

```csharp
void Snapshot(string changeTitle)
```

> **Obsolete.** Auto Snapshotting is obsolete and no longer working. If you really want to use snapshotting for Undo, create/restore the snapshots manually in the undo/redo actions provided to UndoSystem.Insert

Should be called after you make a change to your project. The snapshot system
is good for self contained projects that can be serialized and deserialized quickly.

### Parameters

- `changeTitle` (`string`)

Declared in [Sandbox.Helpers.UndoSystem](/api/Sandbox.Helpers.UndoSystem).
Assembly: `Sandbox.Tools`.
