At any time, you can change the Scene view in a number of ways, depending on whether you have a 3-button, 2-button, track pad, or a Mac with only one button. Read up on it in the Unity manual (http://docs.unity3d.com/Manual/SceneViewNavigation.html) to find what works for you.

In general, combinations of left/right mouse clicks with the Shift/Ctrl/Alt keys will let you:

• Drag the camera around
• Orbit the camera around the current pivot point
• Zoom in and out
• Alt + right-click the mouse to swing the current eye orbit up, down, left, or right
• When the hand tool is selected (upper-left icon bar), the right mouse button moves the eye (the mouse middle-click does a similar move)

In the upper-right of the Scene panel, you have the Scene view gizmo, which depicts the current scene view's orientation. It may indicate, for example, a perspective view with X extending back to the left and Z extending back to the right:

You can change the view to look directly along any of the three axes by clicking on the corresponding colored cone. Clicking the small cube in the center (or the text beneath the gizmo) changes between a perspective view and an orthographic (nondistorted) view. Note that this only affects your Scene Editor view, not the perspective that your app camera will render when it's running:

That covers some of the basics of using the Unity Editor to create and transform objects in the Scene.

Also, as you will see, objects can be grouped together by dragging one object onto another object in the Hierarchy tree, creating a parent-child relationship between them. Moving, rotating, and scaling the parent will transform the target object and all its child objects together as a group.

Explore the GameObject menu from the Main Menu to see the many kinds of things you can add to your scene.
