Do you want to explore 3D models on your Windows 10 PC? Microsoft 3D Viewer is the perfect tool for the job. This built-in app allows you to open, view, and manipulate 3D models with ease. Here's how it works:

1. Opening 3D Files: Microsoft 3D Viewer supports various 3D file formats, including .fbx, .obj, .stl, and more. You can simply double-click on a 3D file to open it in the 3D Viewer app.

2. Navigating 3D Models: Once the 3D model is open, you can use the on-screen controls to rotate, pan, and zoom in on the model. This allows you to view the model from different angles and perspectives.

3. Adding Annotations: Microsoft 3D Viewer also lets you add annotations to your 3D models. You can place markers, lines, and even text to highlight specific parts of the model or provide additional information.

4. 3D Printing: If you have a 3D printer, you can use Microsoft 3D Viewer to prepare your 3D models for printing. The app allows you to check and adjust the model's orientation and size before sending it to the 3D printer.

5. Sharing and Exporting: Once you've made changes or annotations to a 3D model, you can save the modified version or share it with others. Microsoft 3D Viewer gives you the option to export the model as a new file or directly send it via email.

In conclusion, Microsoft 3D Viewer is a versatile tool for anyone working with 3D models on Windows 10. Whether you're a hobbyist exploring 3D printing or a professional creating 3D designs, this app provides essential features for opening, viewing, and interacting with 3D models.
