If you're using Revit for architecture or design, you may need to export your 3D models to use in other applications. One popular file format for 3D modeling is OBJ, and exporting OBJ from Revit is a straightforward process. Here's how to do it:

1. Open your Revit project and navigate to the 3D view that you want to export.

2. Click on the 'File' menu and select 'Export' > 'CAD Formats'.

3. In the export dialog, select 'Wavefront .OBJ' as the file format.

4. Choose a location to save the OBJ file and click 'OK' to start the export.

5. Once the export is complete, you can now use the OBJ file in other 3D modeling and design applications.

It's important to note that when exporting to OBJ, Revit will create an OBJ file and an associated material file (MTL). These files will contain information about the 3D model's geometry and materials, allowing you to maintain the appearance of the model when using it in other applications.

Exporting OBJ from Revit is a great way to leverage your 3D models for visualization, rendering, and even 3D printing. By following the simple steps outlined above, you can seamlessly integrate your Revit models into your design workflow and collaborate with others using different 3D modeling tools.

In conclusion, understanding how to export OBJ from Revit can expand your options for using 3D models and streamline your design process. Whether you're working on architecture, interior design, or any other type of project, being able to export your Revit models to OBJ format opens up new possibilities for visualization and collaboration.
