Orthographic view has no perspective, and is useful in combination with clicking one of the conical axis arms to get a front, top or side elevation. To do this, click the cube in the centre of the Scene Gizmo, or the text below it. This changes the projection mode of the Scene View between Perspective and Orthographic (sometimes called ‘isometric’). You can also toggle Perspective on and off. To return to the default viewing angle, right-click the Scene Gizmo and click Free. You can also right-click the cube to bring up a menu with a list of viewing angles. Click on any of the conical axis arms to snap the Scene View Camera to the axis it represents (for example: top view, left view and front view). The arms at the forefront are labelled X, Y and Z. The Scene Gizmo has a conical arm on each side of the cube. This displays the Scene View Camera’s current orientation, and allows you to quickly modify the viewing angle and projection mode. The Scene Gizmo is in the upper-right corner of the Scene View.
The Scene View has a set of navigation controls to help you move around quickly and efficiently.
