How to convert 3DS to OBJ
3DS is a 1990s mesh format with hard limits — 65,536 vertices per mesh and eight-character material names — which is why asset libraries full of 3DS files need converting before they are usable in modern visualisation or CAD work.
Why there is no uploader on this page
3DS is a closed format that no browser can read, so an in-page converter would have to send your file to a server. The procedure below does the job properly in the application that owns the format — and where a browser-side route exists, it is linked underneath.

Schritt für Schritt
- 1Blender: File → Import → 3D Studio (.3ds), then File → Export → Wavefront (.obj).
- 23ds Max: open or merge the .3ds, then export OBJ; this preserves the material assignments most faithfully.
- 3Batch work: MeshLab converts folders of 3DS to OBJ and can decimate heavy meshes at the same time.
- 4After conversion, check the scale against a known dimension — 3DS files carry no reliable unit.
- 5From OBJ, use our browser-based OBJ to DXF converter to bring the geometry into AutoCAD or Revit.
Worauf Sie achten müssen
- Meshes over the 65,536-vertex limit were split when the 3DS was written, so expect fragmented objects to re-join manually.
- Material names truncated to 8.3 in the original cannot be recovered; re-map them after import.
- Smoothing groups become per-face normals, so re-apply smoothing in the target application.
- Legacy 3DS files often have flipped or inconsistent normals — run a recalculate-normals pass.
The legacy 3D Studio mesh format. Still common in asset libraries, limited to 65,536 vertices per mesh and 8.3 material names.
A plain-text mesh format listing vertices and faces — openly documented, which is why it can be read and rewritten in the browser.
Fragen aus der Praxis
Is 3DS worth keeping as an archive format?
No. Convert your library to OBJ, FBX or glTF; 3DS limits both vertex count and material naming.
Does converting to OBJ improve quality?
It removes the format limits but cannot add detail. Geometry quality stays whatever the 3DS held.
Can I get 3DS into AutoCAD directly?
Convert to OBJ first, then use our OBJ to DXF converter, which runs in your browser with no upload.
