Convert OBJ to DXF in your browser
OBJ is one of the few 3D formats that is plain text and fully documented, so this conversion runs entirely in your tab: the mesh is parsed here and written out as DXF 3DFACE entities that AutoCAD, BricsCAD, Civil 3D and Revit all import. Nothing is uploaded and nothing is queued.

TaskBider drafters, detailers and BIM coordinators work remotely and every listing shows the pay. Typical published range for this work: $18–$45/hr.
خطوة بخطوة
- 1Drop the .obj file above. Large meshes take a moment — the parsing happens on your machine, not on a server.
- 2Download the DXF and open it in AutoCAD with the units set to match the OBJ authoring units (OBJ carries no unit declaration).
- 3Use 3DORBIT and SHADEMODE to confirm the mesh arrived the right way up; Y-up authoring tools land on their side in a Z-up CAD drawing.
- 4For a 2D deliverable, set a plan view and run FLATSHOT or SECTIONPLANE to generate clean linework from the mesh.
أمور يجب الحذر منها
- Triangles and quads convert directly; faces with more than four vertices are triangulated so nothing is dropped.
- Materials, textures and UVs are not part of DXF geometry, so an accompanying .mtl file is ignored.
- A mesh is not a solid. If you need a watertight solid for machining, convert through STEP in the originating CAD package instead.
- Very dense scan meshes produce huge DXFs — decimate in MeshLab or Blender first if the drawing becomes unworkable.
A plain-text mesh format listing vertices and faces — openly documented, which is why it can be read and rewritten in the browser.
Autodesk's documented text interchange format for 2D/3D CAD geometry — readable by every CAD package and, unlike DWG, by open-source tools.
أسئلة يطرحها الرسامون الفنيون
Is my OBJ uploaded anywhere?
No. The file is read and the DXF is written by JavaScript in your browser, so the model never leaves your machine.
Why is my model lying on its side in AutoCAD?
Most 3D content tools are Y-up while CAD is Z-up. Rotate 90 degrees about the X axis after import, or set the up-axis when exporting the OBJ.
Can I get solids instead of a mesh?
Not from OBJ — it only stores surface triangles. Export STEP from the source CAD system if you need an editable solid.
What scale does the DXF come out at?
One OBJ unit becomes one drawing unit. Because OBJ has no unit field, set the drawing units yourself or scale the block after insert.
