How to convert DWG to OBJ
- Add your .DWG file - drop it in the box above or click to browse.
- Convert it to .OBJ in a few seconds.
- Download your new .OBJ file.
What to expect
- 3D geometry is tessellated to triangles; layers, blocks, dimensions and exact curves are dropped.
- Expect an untextured grey model, since no .mtl materials come from CAD geometry.
- 2D-only drawings produce no usable 3D mesh.
Frequently asked questions
What kind of model does DWG to OBJ produce?
OBJ is a plain-text list of vertices, faces and normals, so 3D solids become a triangle mesh. CAD precision, layers and the ability to edit parametrically are lost.
Why convert DWG to OBJ?
OBJ is a widely supported open mesh format for 3D viewers, rendering and print preparation, whereas DWG is not readable in those tools. It is a good bridge from CAD into general 3D software.
Where does the OBJ open?
It opens free in Blender, the Microsoft 3D Viewer on Windows, or a browser-based 3D viewer.
Why does the model look grey and untextured?
Colours and materials in OBJ live in a companion
.mtl file, but CAD geometry has none to export, so the model loads grey. A 2D DWG also has no surfaces to mesh.Programs that convert DWG: PolyTrans|CAD+DCC · LogiKal · 3ds Max (3D Studio Max) · SketchUp · pCon.planner · SketchUp for Mac · Autodesk Fusion 360 · Online CAD converter
