Convert OBJ to DWG (via DXF Projection)

Convert OBJ 3D models to a 2D DXF projection for AutoCAD — free and instant.

📐

DWG export is a Pro feature, coming soon. OBJ to DXF works today, free and instant, and opens directly in AutoCAD.

DWG export is coming as a Pro feature

We're building native DWG export — join the waitlist to be notified at launch.

What would you expect to pay for DWG export?

Wouldn't pay extra $5–10/mo $10–25/mo $25+/mo

Convert to DXF instead — works now, free

✔ What it does

Projects OBJ 3D mesh geometry onto a 2D plane and outputs DXF line entities — free and instant. Extracts outlines, silhouettes, and footprints from 3D models.

✘ What it does not do

Does NOT preserve 3D structure — this is a 2D projection only. Does NOT currently generate DWG output — DWG export is a Pro feature in development (join the waitlist on this page). Does NOT include textures, materials, or depth data.

How to get your DWG file — 4 steps

Upload your OBJ file → click Convert → download the DXF file
Open the DXF file in AutoCAD (File → Open)
Go to File → Save As → select DWG format
You now have a native DWG file

Why DXF, not DWG directly? DWG is a proprietary Autodesk binary format. DXF is the open interchange standard that AutoCAD reads natively and converts to DWG in seconds using Save As.

How OBJ → DWG conversion works

OBJ files store 3D geometry as vertices, edges, and faces. This tool loads the OBJ mesh and projects the geometry onto a 2D plane (XY top view by default), extracting visible edge lines and silhouettes as DXF line entities — free and available now. All depth and 3D structure is permanently discarded in the projection. Native binary DWG export is being built as a Pro feature; use OBJ to DXF for a free, working conversion today, or join the waitlist below to be notified when DWG ships. If you need full 3D output, use OBJ → FBX instead.

Limitations

DWG export is not currently available — this page produces DXF only; see OBJ to DXF for the free, working tool.
All 3D depth is permanently lost — output is 2D line geometry only.
Textures, materials, and UV data from the OBJ are not present in DXF output.
Dense polygon meshes may produce complex, hard-to-edit DXF line work.

When to use this conversion

Extracting floor plan footprints from 3D models for architectural drawings.
CNC cutting guide outlines from 3D product models.
Architectural silhouettes for 2D drawing reference.
Flat-pattern fabrication templates from 3D geometry.

Alternatives to consider

OBJ → FBX on this site if a full 3D format is needed for game engines.
FreeCAD's Drawing Workbench for engineering-accurate 2D drawings from 3D geometry.
Blender (File → Export → DXF add-on) for more projection axis control.

Frequently asked questions

Why is this a 2D output from a 3D model?

DWG in 2D drafting is a flat format. Projecting 3D geometry to 2D is the standard workflow for extracting CAD reference from 3D models.

I need the full 3D model in a compatible format — what should I use?

Use OBJ → FBX on this site for game engines and 3D tools, or STL → OBJ for broader 3D format compatibility.

Why don't I get DWG directly?

Native DWG export is a Pro feature currently in development — join the waitlist on this page to be notified at launch. OBJ to DXF produces the same 2D projection, free and instant.
