Revit is a powerful tool for creating 3D models and architectural designs, but sometimes you may need to export your designs to use in other 3D modeling and rendering applications. One common file format for this purpose is the OBJ file format, which is widely supported by many 3D software applications. In this article, we will guide you through the steps to export OBJ files from Revit.

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

2. Go to the 'File' menu and select 'Export' > 'CAD Formats'.

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

4. Click 'Options' to configure the export settings. Here, you can specify the units, coordinate system, and other export options.

5. Once you have configured the export settings, click 'OK' to close the options dialog box.

6. Choose a location on your computer to save the OBJ file, and enter a name for the file.

7. Click 'Save' to export the OBJ file from Revit.

Now you have successfully exported your 3D model from Revit to an OBJ file. You can import this file into other 3D modeling and rendering applications to continue working on your designs. OBJ files are versatile and widely supported, making them a great choice for transferring 3D models between different software applications. Whether you are collaborating with other designers or working on rendering and visualization, exporting OBJ files from Revit can help you seamlessly integrate your designs into different workflows.
