Hey there! Are you interested in exploring 3D models on your Windows 10 computer? The 3D Viewer app allows you to do just that. Here's a quick tutorial on how to use this cool feature:

1. Open the 3D Viewer App:

- Click on the Start menu and search for '3D Viewer.'

- Click on the app to open it.

2. Explore 3D Models:

- Once the app is open, you can explore pre-loaded 3D models or import your own by clicking on the 'Open' button.

3. Manipulate the Model:

- Use your mouse or touchpad to rotate the 3D model to view it from different angles. You can also zoom in and out using the scroll wheel or pinch-to-zoom gestures.
