While working in 3D, there are many ways to change how you view your drawing. Views are seen by the "camera" - equivalent to your eye. The camera is located in a specific place and faces a specific direction. See The Camera.
There are several standard orthographic and isometric views, and if you need additional perspective you can change how the camera is oriented. You can move the camera using the Move Camera commands (see Camera Movements), and dynamically examine the model using the Walk Through tools (see Walk Through Tools). To save and display additional views, you can create camera objects (see Camera Objects).
Tip: If y ou use a wheel mouse, keep the middle mouse button pressed, and drag the cursor around the screen to dynamically rotate the model.
