Sketch to floor plan

Redraw a hand sketch, scan or photo of a plan as a clean 2D floor plan.

Sketch to floor plan redraws a layout as a clean 2D plan on a blank sheet: a pencil sketch, a phone photo of a printed or old plan, a scan, a tablet drawing or a screenshot. It is a faithful copy of the layout, not a redesign — the same outline, the same rooms and walls, the same proportions — with wobbly lines straightened and right angles squared. Agents use it to turn a seller's sketch into a listing plan; builders, landlords and architects use it to get a presentable plan from paper.

Options

Option	Type	Values	Default	Required	Description
`measurementMode`	string	`preservenoneai_guess`	`none`	optional	Dimensions: `preserve` keeps the numbers the drawing has (an unreadable one is left out), `none` leaves them all out, `ai_guess` keeps them and estimates missing ones — approximate only.
`labelMode`	string	`preservenoneai_locale`	`none`	optional	Room names: `preserve` keeps the drawing's names, `none` leaves names out, `ai_locale` keeps them and names other rooms where it can tell, in the `locale` language.
`furnitureMode`	string	`preservenoneai_standard`	`none`	optional	Furniture: `preserve` keeps what the drawing shows, `none` draws walls, doors and windows only, `ai_standard` keeps drawn furniture and adds standard pieces to empty rooms.
`outputStyle`	string	`line_artgrey_fillshatchedsymbolized`	`line_art`	optional	`line_art` black on white (CAD look), `grey_fills` dark walls and light grey rooms, `hatched` diagonally hatched walls, `symbolized` pastel rooms with furniture symbols.
`pageSize`	string	`matcha4_landscapea4_portraitsquarewide_16_9`	`a4_landscape`	optional	Shape of the sheet: 3:2, 2:3, 1:1 or 16:9; `match` is the same 3:2 sheet as a4_landscape. Pick a4_portrait for a tall drawing — on a landscape sheet the model may turn it sideways.
`openings`	string	`as_drawncomplete`	`as_drawn`	optional	`as_drawn` keeps only the doors and windows the drawing shows; `complete` also adds the obvious missing ones.

Every option has a default, so a request with no options draws a black-and-white line plan on an A4 landscape sheet with no dimensions, no room names and no furniture, and with doors and windows only where the drawing shows them. To keep what the drawing says, ask for it:

What the drawing keeps

The outline, the number of rooms and the walls between them; no room is added, merged or split.
Stairs, columns, shafts and the other structural symbols the drawing shows, in their places.
Every door and window the drawing marks, whatever symbol it uses, redrawn with the standard symbol. With openings as_drawn (the default) an unmarked gap in a wall stays an open passage; complete lets the model add the doors and windows the layout obviously needs.
More than one floor on the sheet: each floor drawn as its own plan, in the same arrangement.

Paper edges, folds, shadows, fingers, graph-paper grids and watermarks are not part of the plan and are left out. A photo taken sideways is turned upright from its EXIF orientation first.

Text and furniture

Each of measurementMode, labelMode and furnitureMode has the same three choices: keep what the drawing has (preserve), leave it out (none), or keep it and let the model fill the gaps (ai_guess, ai_locale, ai_standard).

Dimensions and room names are copied from the drawing, and one the model cannot read is left out — check them against the original before you publish.
Estimated dimensions (ai_guess) are approximate. Measure, or leave them out.
Room names the model adds (ai_locale) are written in the language of locale, an extra key next to the options: en, tr, de, es, fr, ja, pt-BR, ru or zh (regional forms such as de-AT work too). Without it, or for any other language, they are in English.
Added furniture (ai_standard) follows standard layouts, not a designer's judgement.

Page and style

pageSize picks the shape of the sheet: A4 landscape (3:2, the default), A4 portrait (2:3), square or 16:9. The plan is centred and scaled to fit with even margins, never stretched. Pick a4_portrait for a tall drawing: on a landscape sheet the model may turn it sideways.

outputStyle picks the drawing style: pure black line art, dark walls with light grey rooms, diagonally hatched walls, or pastel rooms with furniture symbols.

There is no custom prompt for this tool, and tier auto draws the default plan, using only pageSize from what you send. Use the options.
