Convert REVIT to OBJ

Source format: Revit

Revit is Autodesk’s BIM authoring software used for architectural, structural, and MEP design. Revit projects are typically saved as .rvt files, with families in .rfa and templates in .rte. These files store intelligent building elements such as walls, doors, floors, rooms, schedules, and metadata, not just geometry.

Target format: OBJ

OBJ is a widely supported 3D mesh format used for exchanging surface geometry between modeling, rendering, visualization, and game or animation tools. It stores polygonal meshes and can reference a companion .mtl file for materials and texture links. OBJ is popular because it is simple, broadly compatible, and easy to import into many applications such as Blender, 3ds Max, Maya, SketchUp, and many visualization engines.

How to convert Revit to OBJ

Revit does not export directly to OBJ in the standard desktop application, so the usual workflow is to export from Revit to an intermediate format and then convert that file to OBJ with a dedicated 3D tool. In many cases, FBX is the best intermediate choice because it often preserves scene structure and materials better than simpler mesh formats.

1. Export from Revit
   Open the model in Revit and export to a mesh-friendly format such as .fbx. Depending on your workflow, .dwg or .sat may also be available, but FBX is usually the most practical option for OBJ conversion.
2. Import into a conversion tool
   Open the exported file in Blender, Autodesk 3ds Max, SimLab Composer, Okino PolyTrans, or another converter. In Blender, use File → Import → FBX for FBX files.
3. Check scale and orientation
   Revit models often use architectural units and may import with a different axis orientation or scale. Verify the model size, rotation, and placement before exporting.
4. Clean and optimize the mesh
   OBJ is a polygon mesh format, so BIM intelligence is lost. Remove unnecessary hidden objects, simplify overly dense geometry, and confirm that materials and textures are assigned correctly.
5. Export as OBJ
   In Blender, use File → Export → Wavefront (.obj). In 3ds Max, use File → Export → Export Selected and choose OBJ if the exporter is installed. Enable options for materials and texture coordinates if needed, then save the file as .obj.

Direct export options

Some third-party plugins can export Revit models to OBJ more directly, but availability and quality vary by version and vendor. If you use a plugin, confirm that it supports your Revit release and test the output on a small model first. For many users, a Revit-to-FBX-to-OBJ workflow is more predictable.

Recommended tools

• Blender — best free desktop option for importing common intermediate formats and exporting OBJ reliably.
• Autodesk 3ds Max — strong professional choice for architectural visualization workflows.
• SimLab Composer — useful for BIM-to-mesh conversion and presentation workflows.
• Okino PolyTrans — good for controlled conversion and handling complex scenes.

Online converters

Reputable online conversion services are less ideal for large Revit models because BIM files are heavy and may contain sensitive project data. If you must use an online service, choose one that explicitly supports Revit or FBX-to-OBJ conversion and review its privacy policy before uploading. For professional work, a desktop workflow is strongly preferred.

Notes on quality and limitations

Revit to OBJ is a lossy conversion. OBJ cannot preserve Revit’s parametric behavior, schedules, constraints, view settings, or most BIM metadata. Only visible geometry and some material information are typically retained. Complex families may be tessellated into dense meshes, which can increase file size and reduce performance. Textures may need manual relinking, and some Revit elements may not convert cleanly if they rely on procedural or parametric features.

For best results, export only the views or categories you need, use a clean model, and keep expectations focused on visualization and interchange rather than BIM editing. If your goal is rendering or real-time visualization, OBJ is suitable; if you need editable BIM data, consider a format such as .ifc instead.
