What is the DXF file format?
DXF (Drawing Exchange Format) is an open CAD format Autodesk published in 1982 so AutoCAD drawings could move to other programs. Unlike DWG, its structure is documented, in ASCII and binary form.
Almost every CAD and GIS program reads and writes DXF, including AutoCAD, BricsCAD, QCAD, LibreCAD, FreeCAD, Rhino and SolidWorks. It keeps lines, arcs, circles, splines, text, dimensions, hatches, blocks and layers.
Because the format is open, this viewer reads the file directly in your browser with WebGL.
Need to open a DWG file?
The DWG viewer opens AutoCAD files without AutoCAD.
