If you're working with Maya for 3D modeling, you may want to export your creations as OBJ files for use in other programs or for sharing with others. Here's a step-by-step guide on how to export your Maya models as OBJ:

1. Open your Maya project and ensure that your 3D model is ready for export. Make any necessary adjustments or clean-up before proceeding.

2. With your 3D model selected, go to File > Export Selection. This will bring up the Export Selection window.

3. In the Export Selection window, choose 'OBJexport' from the Files of Type drop-down menu. This will ensure that your model is saved as an OBJ file.

4. Specify the file name and location where you want to save the OBJ file. Choose a descriptive name that will help you identify the model later.

5. Click on the Export button to save your model as an OBJ file. You may be prompted with additional settings depending on the complexity of your model. Adjust these settings as needed.

6. Once the export is complete, navigate to the location where you saved the OBJ file. You can now use this file in other 3D modeling programs or share it with others.

By following these steps, you can easily export your Maya 3D models as OBJ files for use in other programs or for sharing with others. This simple process allows you to make the most out of your Maya creations and collaborate with others in the 3D modeling community.
