If you're a 3D artist or designer using Autodesk Maya, you may need to export your 3D models in OBJ format for use in other software or to share with others. Fortunately, Maya makes it easy to export your models as OBJ files. Here's a simple step-by-step guide to help you export as an OBJ in Maya.

1. Select the Object: First, open your Maya scene and select the 3D model or object that you want to export as an OBJ file.

2. Navigate to File Menu: Once the object is selected, navigate to the 'File' menu at the top-left corner of the Maya interface.

3. Choose Export All: In the 'File' menu, select the 'Export All' option. This will open the Export All Options window.

4. Set File Type: In the Export All Options window, you can set the 'Files of Type' to 'OBJexport' to filter the file types.

5. Set Export Location: Choose the destination folder where you want to save the OBJ file. You can also set the file name and other export options in this window.

6. Export Options: Maya provides various export options for OBJ files, including smoothing groups, triangulate, and materials. Make sure to adjust these settings according to your requirements.

7. Export the File: After setting the export options, click on the 'Export All' button in the Export All Options window to export the selected object as an OBJ file.

8. Open in Other Software: Once the OBJ file is exported, you can open it in other 3D software such as Blender, 3ds Max, or Unity for further editing or use.

By following these simple steps, you can easily export your 3D models as OBJ files in Autodesk Maya. Whether you're collaborating with other designers or preparing your models for use in different software, exporting as an OBJ file allows for seamless integration and sharing of your 3D creations.
