MS 3D Viewer is a versatile application that allows users to view and interact with 3D models in various formats. The software supports a wide range of file types, making it a useful tool for professionals and hobbyists alike.

One of the most commonly supported file formats by MS 3D Viewer is .obj, which is a popular 3D model format used for storing geometric data. This means that users can easily open and view .obj files with the 3D Viewer application, making it a convenient choice for those working with this file format.

In addition to .obj files, MS 3D Viewer also supports other common 3D model formats such as .stl, .fbx, .3ds, and .dae. This broad range of supported file types makes the application a valuable asset for anyone working with 3D models, as it eliminates the need for separate software for each file format.

To open a supported file type in MS 3D Viewer, users can simply navigate to the file location on their computer and double-click on the file. This will launch the 3D Viewer application and load the 3D model for viewing and interaction. Alternatively, users can also use the 'Open' option within the application to select and open a specific file.

Once the file is loaded in MS 3D Viewer, users can take advantage of its intuitive interface to manipulate and interact with the 3D model. The application provides various tools for zooming, rotating, and panning the view, allowing users to examine the model from different angles and perspectives.

Furthermore, MS 3D Viewer also offers features for changing the rendering mode, applying textures, and adjusting the lighting settings to enhance the visualization of the 3D model. These capabilities make the application a powerful tool for visualizing and presenting 3D designs and concepts.

In conclusion, MS 3D Viewer supports a diverse range of file types, including .obj, .stl, .fbx, .3ds, and .dae, making it a valuable resource for viewing 3D models. The application's user-friendly interface and extensive feature set further enhance its utility, making it a compelling choice for professionals and enthusiasts working with 3D designs.
