3D modeling enthusiasts often use .obj files to save and share 3D models with others. While Maya is a popular software for working with 3D models, it is not the only option for opening .obj files. Here are a few alternative methods to open .obj models without using Maya.

1. Blender: Blender is a free and open-source 3D creation suite that supports the importing of .obj files. Users can simply open Blender, go to 'File' > 'Import' > 'Wavefront (.obj)' and select the desired .obj file to open it in the software.

2. Autodesk FBX Review: Autodesk FBX Review is a lightweight and standalone software that allows users to view 3D models in various formats, including .obj. Simply download and install FBX Review, then open the software and use the 'File' menu to open the .obj file.

3. MeshLab: MeshLab is a powerful open-source 3D mesh processing software that supports the importing and viewing of .obj files. Users can open MeshLab, go to 'File' > 'Import Mesh' and select the .obj file to open it in the software.

4. Windows 3D Viewer: Windows 10 comes with a built-in 3D Viewer app that can open .obj files. Users can simply right-click on the .obj file, select 'Open with' and choose '3D Viewer' to open and view the 3D model.

5. Online obj Viewer: There are various online tools and websites that offer the ability to upload and view .obj files directly in the web browser. Users can search for 'online obj viewer' and choose a trusted website to upload and view their .obj models.

By using these methods, 3D modeling enthusiasts can easily open and view .obj models without the need for Maya or other expensive software. Whether it's for simply viewing the model, making minor edits, or sharing with others, these alternative methods provide convenient options for working with .obj files.
