Free IFC to OBJ converter
Convert IFC models to OBJ.
Get a BIM model from Revit, ArchiCAD or Tekla into Blender, SketchUp, Twinmotion or a game engine. Drop an IFC file and download an OBJ, with building elements as named groups when the model provides them.
Why convert IFC to OBJ?
Visualisation, rendering and VR tools want meshes, not BIM data. IFC is the open format every BIM tool exports, so it's the usual starting point.
How to convert IFC to OBJ
- Choose your IFC file above, or drag it onto the box.
- Check that OBJ is selected. You can switch to any other output.
- Select Convert. The file downloads straight away. Nothing is uploaded.
Good to know
- Properties, classifications and other BIM data are not included. The OBJ is geometry only.
- IFC models are usually in metres or millimetres. Check the scale after importing.
What converts, and what doesn't
- Every output is a triangle mesh. STEP and IFC solids are tessellated for display, so the result is not an editable solid or B-rep.
- When the source names its parts (STEP and IFC assemblies, for example), they become named groups in OBJ. STL, PLY and GLB hold a single combined mesh.
- Colours and materials are not carried over.
- Coordinates keep the source units, except GLB, which is scaled to metres when the source declares its units.
Frequently asked questions
Which IFC versions are supported?
IFC2x3 and IFC4 geometry. Use the free version checker to see a file's schema.
Is my file uploaded?
No. The file is read and converted by the Caddis engine running inside your browser tab. It is never sent to a server, so confidential drawings stay on your device.
Is it really free?
Yes. There's no account, watermark, page limit or daily quota. The converter runs on your own computer, so it costs us nothing per file.
Need to measure or mark up the drawing too?
The same engine powers the free Caddis viewer on the web and on iPhone. Open DWG, DXF, STEP and STL files, measure, and add markup, all on your device.
