- 7
Keep a copy
Tap Save Project File.
The project file downloads to your phone (layout-rooms-2026-09-23.json).

What result should I expect?
A room layout that fits your footprint, with doorways, furniture placed and anything tight flagged, in plan and 3D. Every room stays editable — tap it to resize, move or rename.
How do I save, share or get help?
On Save: Save Project File downloads the whole plan; Share a link; Create an image of this layout; Send to a designer / architect; Confirm this layout. Signed in, Save to my project keeps it in your account.
If something goes wrong
- No layouts came back. Mark the beam, posts, stairs and mechanical on step 1 first — they decide where walls can go — or ask for fewer rooms.
- A piece is flagged red. Something blocks its clearance (a door swing, the panel's keep-clear zone). Hold and slide it, or furnish that room again.
