Convert OBJ to DXF (2D Projection for CAD Reference)
Convert OBJ 3D models to 2D DXF projection for AutoCAD reference and drafting. Understand what is produced and what 3D data is lost.

How OBJ → DXF conversion works
OBJ files store 3D geometry as vertices, edges, and faces, along with optional UV coordinates and material references. This tool loads the OBJ mesh (and accompanying MTL file if provided) and projects the geometry onto the XY plane (or a specified axis). Edge lines and silhouettes visible from the projection direction are written to DXF as 2D LINE and POLYLINE entities. UV coordinates and texture data from the OBJ are not present in DXF output — DXF is a geometry-only format. The output is suitable as a CAD reference layer, a silhouette guide, or a 2D footprint extraction from a 3D scan.
Limitations
- All depth information is permanently lost — output is 2D only.
- UV coordinates and texture data from the OBJ are not present in DXF.
- Dense polygon meshes may produce complex, hard-to-edit DXF line work requiring cleanup.
When to use this conversion
- Extracting a 2D footprint from an OBJ model for architectural drawings.
- Using a 3D scan outline as a reference layer in AutoCAD.
- Creating a silhouette guide from an OBJ model for CNC cutting or laser engraving.
Alternatives to consider
- Blender's Freestyle line rendering for visually accurate 2D-from-3D output.
- FreeCAD for engineering-accurate 2D drawings from 3D OBJ geometry.
Frequently asked questions
Is this the same as OBJ to DWG?
Functionally similar. Output is DXF, which can be opened in AutoCAD and saved as DWG from there using File → Save As.
Will materials or textures appear?
No. DXF is a geometry-only format. All material and texture data from the OBJ is discarded.
Can I select the projection angle?
XY (top view) by default. Pro tier supports XZ and YZ axis selection.
