A note on calibration
The file is exported to real-world millimetre scale after manual calibration on two known points selected on the vector preview. Regeneration to scale happens server-side, using a library that writes structurally valid DXF: the downloaded file is never rewritten by the browser, avoiding the corruption typical of text-based manipulation of the DXF format.
