The Cloud is just somebody else's computer
Storage
Your work lives in workspaces, and you choose where each one is stored: in your browser with no account (the default), as files in a folder on your computer, or in a cloud workspace you can open from any device once you sign in.
Each part is one .cubby file holding the scene graph, sketches, undo history, metadata and a thumbnail. Autosave runs on every storage option.
How to use it
Open the workspace chooser
The Choose where to work dialog opens on first launch (or from ). Pick one of three options.
Use browser storage
Browser storage (recommended) works right away with no account. Parts are saved in this browser only.
Sync to the cloud
Cloud workspace: sign in, then create or pick a workspace to sync parts across devices. Signed-out users can still browse public workspaces read-only.
Save to a local folder
Open a folder on this computer: choose a folder and parts are written there as .cubby files. Needs a browser with the File System Access API.
Work with autosave
Autosave runs about 1.5 seconds after you stop editing, and at least every 30 seconds while you keep going. Ctrl+S forces a save, and Ctrl+Shift+S is .
Watch the status pill
The status pill at the bottom right reads Unsaved changes, Saving…, then Saved just now / Saved Xs ago, or Save failed if something went wrong.
Tips
- Autosave only runs once a part has a destination. Brand-new drafts, unsaved script edits and un-applied mesh repairs are not autosaved.
- Switching workspaces with unsaved drafts asks you to confirm before anything is discarded.
- Closing the tab while a save is still running triggers the browser's "leave page?" prompt.
- A .cubby file is one part. Imported meshes and custom fonts are stored next to it in the workspace and referenced by the part, so keep them together.
- The chooser highlights your last destination but never picks it for you.
