Convert OBJ to DXF
Convert a OBJ file to DXF in your browser. Free, no upload, no sign-up.
Convert OBJ files to DXF directly in your browser. The converter parses the OBJ mesh, rebuilds it in memory and writes it out as DXF, keeping every triangle. Nothing is uploaded, there is no file size limit beyond your computer's memory, and the result downloads instantly. DXF is what 2D CAD software, laser cutters and CNC routers read, and AutoCAD imports a mesh from it with no plugin.
How to convert OBJ to DXF
- 1Drop your OBJ file
Drag a .obj file onto the box above or click to choose one. The companion .mtl file and textures are ignored. Geometry is imported completely.
- 2Check the preview
The model renders in 3D so you can confirm it loaded correctly. Dimensions, volume and triangle count are shown next to it; open edges are flagged if the mesh is not watertight.
- 3Download the DXF
Adjust the export options if needed and click download. The mesh is written as 3DFACE triangles in millimeters. Colors, textures and materials are dropped, and the result is a faceted mesh rather than editable CAD curves.
What is a OBJ file?
OBJ is a plain-text mesh format from Wavefront. It stores vertices, normals, UV texture coordinates and face definitions, and references materials through a companion .mtl file. It is human-readable and supported by virtually every 3D modelling application.
Commonly used by: Blender, Maya, ZBrush, game engines, photogrammetry tools
The companion .mtl file and textures are ignored. Geometry is imported completely.
What is a DXF file?
DXF is the open interchange format Autodesk published for AutoCAD in 1982. Most DXF files are 2D drawings: lines, arcs, polylines and text on layers. Some also carry 3D geometry as 3DFACE entities. It is what 2D CAD, laser cutters and CNC routers exchange.
Commonly used by: AutoCAD, LibreCAD, QCAD, Laser cutters, CNC routers, Fusion 360 sketches
