From sketch to wall: how auto-trace works

Not every project starts from a blank room program. Sometimes you've already got a hand-drawn sketch, a photo of a whiteboard, or an old plan on paper, and redrawing it wall-by-wall is the last thing you want to do. Floor Plan Studio's sketch-capture tool turns that image into a rough set of editable wall geometry directly in the browser — no vision-model API key required, and the output is clearly labelled a rough estimate from the moment it lands on the canvas.

The capture also places a trace-over underlay from the same image, so you can see exactly where the auto-traced walls diverge from the original sketch and nudge them into place. If the image has a known real-world scale (a dimension string, a door you know is 900mm), the underlay calibrator lets you rescale the whole thing by drawing one line of known length — after which everything you trace lines up with real-world measurements instead of guesswork.

It's meant for getting a rough starting layout onto the canvas fast, not for precision digitization of an existing as-built survey — treat the traced walls the same way you'd treat any AI-generated scheme: a starting point you refine, not a finished drawing.
