About converting SXF(P21) to SVG
P21 is the formal file type of SXF, the Japanese public-works CAD exchange standard based on ISO 10303 (STEP). If you received .p21 drawings from a Japanese client, very few tools outside Japan can open them.
SVG is a vector format, so lines stay sharp at any zoom level. It's ideal for embedding drawings in web pages or editing them in Illustrator and other design tools.
All conversions run through a single engine with a common intermediate representation. Every conversion produces a loss report tallying which entities were converted as-is and which were approximated or dropped — so you can trust the output, or know exactly why not.
FAQ

Will my drawing break when converting SXF(P21) to SVG?
The conversion is a deterministic, structural translation through a common intermediate representation. After every conversion you get a loss report listing exactly which entities were converted, approximated, or dropped — so you can verify the result on the spot.
Is there a limit on conversions or downloads?
No. Conversions and downloads are unlimited, and no account is required. The only limit is 10MB per file.
