Walkthrough Assistant lets you easily create a predefined walkthrough animation of your scene by placing a camera on a path and setting the height, turning the camera, and viewing a preview. This feature is available on the Animation Menu.
In a scene, create a path for the camera to follow using a spline or NURBS curve. Then choose Walkthrough Assistant from the Animation menu. With Walkthrough Assistant you can automatically create a camera and animate it along the path. Change a Perspective viewport into the Camera viewport to view the result. You can adjust the eye height and head tilt. You can animate turning the camera by turning on the Auto Key button. For more information see .
