Duplicate first, then change things
Any time you're about to try something you're not sure about — moving the kitchen, testing a bigger footprint, opening up the ground floor — make a copy and work on the copy. Your original stays exactly as it was.
There are three places to do it:
From your projects list — ⋮ on the project row → Duplicate. Copies the whole project, every plan and every render in it.
Inside a project — ⋮ on the plan card → Duplicate. Copies that one plan into the same project.
Inside the editor — the ⌄ next to the plan name → Duplicate. Copies what you're working on and opens it, so you can carry straight on.
Duplicating is available on any paid plan.
Name them as you go
Rename from the ⋮ menu the moment you duplicate, while you still remember what you were testing:
Option A — open kitchen
Option B — kitchen at back
Option B + garage
Group them into folders
Once you're past a handful of plans, folders keep the project readable.
In the project, click + New Folder, name it, and click Submit.
On any plan, click ⋮ → Move to folder and choose where it goes.
Move to folder only appears once you have at least one folder. If it's not in the menu, create the folder first.
Deleting a folder deletes the plans inside it, permanently, and it can't be undone. Move anything you want to keep out of the folder first.
