Rotating the view in AutoCAD 3D can help you get a better perspective of your design and make it easier to work on different parts of the model. Here's how to do it:

1. Use the ViewCube: The ViewCube is a handy tool located in the upper-right corner of the drawing area. Simply click and drag on the ViewCube to rotate your view in the 3D space. You can also click on the corners of the ViewCube to quickly orient your view to different angles.

2. Use the Orbit Command: The Orbit command allows you to freely rotate your view in 3D space. Simply type 'orbit' in the command line and press Enter. Then, click and drag in the drawing area to rotate your view. You can also use the Orbit tool from the View panel in the Ribbon.

3. Use the 3DORBIT Command: The 3DORBIT command gives you more control over your view rotation. Type '3DORBIT' in the command line and press Enter. Then, click and drag in the drawing area to rotate your view. You can also use this command to pan and zoom in 3D space.

4. Use the SteeringWheel: The SteeringWheel is another intuitive tool for view manipulation in AutoCAD 3D. Click on the SteeringWheel icon in the toolbar at the bottom of the drawing area, then click and drag on the SteeringWheel to rotate your view. You can also use the SteeringWheel to pan and zoom.

5. Use the Viewport Controls: If you're working in a layout with multiple viewports, you can use the viewport controls to rotate the view inside each viewport. Simply click on the viewport border, then use the Orbit tool to rotate the view within that specific viewport.

By using these methods, you can easily rotate your view in AutoCAD 3D to get a better understanding of your model and make it easier to work on different parts of the design.
