If you're a 3D artist or designer working in Maya, you may need to export your models as OBJ files for various reasons like sharing with others or using them in different software. Here's a step-by-step guide on how to do it:

1. Open your Maya project and navigate to the model you want to export. Make sure the model is ready for export, including texture maps and UV maps properly applied.

2. Go to 'File' in the menu bar and select 'Export Selection' or 'Export All' depending on whether you want to export the entire scene or just a specific object.

3. In the export settings window, choose 'Wavefront OBJ' as the file type. You can also adjust other export settings like the file name, file path, and options for including material information.

4. After setting the export options, click 'Export' to save your model as an OBJ file.

5. Once the export is complete, you can locate the OBJ file in the specified file path and use it as needed.

By following these simple steps, you can easily export your 3D models from Maya as OBJ files, allowing you to share them with others and use them in various 3D software applications. Remember to always check the export settings to ensure that the OBJ file includes all the necessary information for your specific use case.
