Additional Functions in 3D Views
Apart from the functions mentioned above, you can also zoom in 3D views by holding down the right mouse button and dragging the mouse up or down. This movement corresponds to the functions ‘Zoom in’ and ‘Zoom out’, although here the zooming is continuous and not in predefined steps as with the buttons.
With the aid of the key combination ‘Shift + left mouse button’, you can reposition the scene to prevent the 3D model from sliding out of the window when zooming.
