DXF drawing viewer and repair
A DXF is text: code and value, line after line, with a handful of marker records providing all of the structure. So a drawing whose tail was lost reads perfectly up to the point of the loss — but a CAD program, finding no end marker, refuses to open the file at all. That is where the feeling of a lost drawing comes from, while every line of geometry is still there. This tool treats nothing as required: no end marker, an unclosed section, corrupted lines — each absence is recorded and the read carries on. What could be read is what is shown, and every problem it stepped around is stated plainly.
Drop a .dxf file. One your CAD refuses will do too: truncated, missing its end marker, carrying corrupted lines.
The drawing on a white sheet, with layers you can switch off one at a time. Beside it: the version, the object count and a list of what had to be stepped around.
SVG opens in a browser and in vector editors. The rewritten DXF is the same drawing written out again by the rules of the format.
