Import the existing floor plan
Most projects start with a floor plan that already exists, and tracing it manually takes hours.
Bring in a photo of an old paper plan or a PDF, and Synaps traces it for you.
Architectural practice
without the compromise.
Automated floor plan tracing
Automatic perspective & scale correction
Photos come in skewed and at the wrong scale, so Synaps fixes both for you.
After dropping the image in the canvas, the tracer straightens the perspective and sets the correct scale automatically, landing within 1 to 2% of the original.
Hand off editable deliverables
What you get back is a real drawing, not a re-stylized flat image.
After the floor plan is traced you can style it to match your standards, the same way you would with any plan you drew yourself.
Questions automated floor plan tracing ask before getting started.
What kind of source material can I trace from?
PDFs, JPGs, phone photos at an angle, scanned blueprints with coffee stains. The trace tool snaps to detected line work in clean inputs and falls back to manual tracing on messy inputs. Most of our users start from a phone photo of an old paper plan and never look back.
How do I correct for perspective distortion in an angled photo?
Drop two known dimensions onto the photo, for example, the length of two adjacent walls, and Synaps de-skews the image so you trace against orthogonal coordinates. The result lands accurate to within 1–2% of the source, which is good enough for renovation and survey work.
Can I trace a plan one room at a time across separate sessions?
Yes. The trace is non-destructive. You can leave a project half-traced, come back tomorrow, and the photo plus your in-progress trace are still aligned. There is no "tracing mode" you can be locked out of.
What is the cleanest way to convert a hand sketch into editable geometry?
Photograph the sketch on a flat surface, set the scale via a labeled dimension on the sketch, then trace the walls. Treat the sketch like a photo background, the resulting geometry inherits no sketchy lines, just clean walls and openings you can develop further.
