Which function helps to fit the model view to the screen?

The function that helps to fit the model view to the screen is achieved by scrolling the mouse wheel. When you scroll the mouse wheel, it typically adjusts the zoom level within the viewing window of the software being used. This action can smoothly transition the view in and out, allowing the user to quickly fit the model view to the dimensions of their screen.

By scrolling the mouse wheel, users can conveniently include more of the model within the viewport, making it easier to see how the elements relate to one another and ensuring all relevant details are visible without needing to pan extensively. This functionality is essential for effective visual navigation and assessment of the model.

In contrast, holding down the mouse wheel generally allows for panning or moving the model around the screen rather than adjusting the zoom level. A right-click commonly serves as a context menu access point, offering various commands specific to the item selected but not directly influencing the fit of the model to the screen. Double-clicking the mouse wheel may initiate specific actions based on the software, such as centering the view on a selected object, but it does not standardly perform the action of fitting the model to the screen like scrolling does.
