What is a .DXF file?
DXF is an open CAD drawing-exchange format readable by almost every CAD program. Created by Autodesk.
- Did you know
- Autodesk created DXF in 1982 as an open way to move drawings between CAD programs.
- DXF stands for Drawing Interchange Format and debuted with AutoCAD 1.0 as a neutral mirror of the proprietary DWG.
- Since AutoCAD Release 10 a binary DXF variant has existed that is roughly a quarter smaller and several times faster to read.
- What Analyser shows you
- Render 2D vector diagrams and CAD drawings to a preview: draw.io / diagrams.net (DRAWIO) files - decoding the mxGraph model, inline or compressed - AutoCAD DXF drawings (parsing the ASCII ENTITIES section), and binary AutoCAD DWG/DWT drawings, parsed by LibreDWG (WebAssembly) into their entities and rendered to an SVG, with an entity and layer breakdown. The thumbnail AutoCAD stored inside the DWG when it was last saved is pulled out alongside it, so even a drawing no CAD engine can open still shows a picture of itself.
- Open a .DXF file
- Drag a .DXF file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
