About dxf-dump

A clean-room reader for DXF drawing files, compiled to WebAssembly. Everything runs in your browser: the file you open is never uploaded anywhere.

The format specification this reader is built from was derived by analysing a corpus of 598 public DXF files and 179 DWG files, not by reading any existing reader's source code.

What it reads

ASCII and binary DXF, versions AC1009 (R12) through AC1032 (R2018)
2-D geometry: lines, arcs, circles, polylines with bulge arcs, ellipses, solids, text and block references
Layers, linetypes, text styles, header variables

What it does not

DWG is identified but not decoded. DWG has no public specification, so geometry extraction is out of scope. Convert to DXF to view it.
3-D entities are preserved but not drawn; splines are shown as their control polygon; hatch patterns are not filled.

Bundled example

example.dxf is a copy of Cad/Bottom.dxf from DanielMartensson/STM32-PLC (MIT), one of the corpus files listed in samples/PROVENANCE.md.
