If you're a 3D artist or designer using Maya, you may often need to share your work with others or collaborate with team members who use different software. One common file format for sharing 3D models is OBJ, which can be easily imported into various 3D software applications. Here's how to export OBJ from Maya:

1. Select your model: Before exporting, make sure the model you want to export is selected in the Maya scene.

2. Navigate to File menu: Click on 'File' in the top menu bar of Maya to open the file options.

3. Choose Export Selection: In the file menu, navigate to 'Export Selection' to open the export dialog box.

4. Select OBJ as file type: In the export dialog box, choose 'OBJ' from the dropdown menu of file types. This will ensure that the exported file is in OBJ format.

5. Set export options: Maya will provide you with various options for OBJ export, such as whether to include material and texture information. Adjust these settings based on your project needs.

6. Choose export location: Specify the folder where you want to save the OBJ file. You can create a new folder for better organization.

7. Name your file: Enter a name for the exported OBJ file. Keep it relevant to the model and easy to identify.

8. Click Export: Once you've set all the options and chosen the export location, click the 'Export' button to generate the OBJ file.

9. Verify the export: After exporting, navigate to the export location to make sure the OBJ file has been created successfully. You can also open the file in a 3D software to check its appearance and functionality.

By following these steps, you can easily export OBJ files from Maya and share your 3D models with others. OBJ files are widely supported and can be imported into applications like Blender, 3ds Max, and Unity, making them a versatile choice for collaboration in 3D projects.
