About the DXF file format
Drawing Exchange Format
DXF was introduced by Autodesk in 1982 as an open, text-based twin of the DWG drawing format. It describes drafting entities — lines, polylines, arcs, circles — and 3D geometry as 3DFACE entities or polyface meshes.
This browser tool renders both: 2D drawings appear as line work, while 3DFACE and polyface entities render as solid meshes.
