If you're working with 3D views in Revit, you may want to rotate the view to get a better angle of your building model. Here's how to do it:

1. Open the 3D View: First, open the 3D view of your building model in Revit. You can do this by selecting the '3D View' tab from the View Control Bar.

2. Rotating the View: To rotate the 3D view, use the navigation tools in Revit. You can use the orbit tool, which looks like a circle with arrows around it. Click and drag with your mouse to rotate the view in the desired direction.

3. Using Shortcuts: Revit also provides shortcuts for rotating the view. Pressing the 'Shift' key and the mouse wheel allows you to orbit the view. Additionally, holding down the 'Shift' key and the middle mouse button while dragging allows you to rotate the view as well.

4. Precise Rotation: If you need to make a precise rotation, you can use the ‘Rotate’ tool under the Modify tab. This allows you to enter the exact angle by which you want to rotate the view.

5. Saving the View: Once you have the desired perspective, you can save the view by creating a new 3D view or updating an existing one. This allows you to easily access the rotated view in the future.

By following these simple steps, you can easily rotate the 3D view in Revit to get the best perspective of your building model. This is especially useful when presenting your model to clients or stakeholders, or when working on detailed design elements. Happy designing!
