In Autodesk Navisworks there are two types of animation: viewpoint animation and object animation.
Viewpoint animation is a quick and efficient way of recording both your movement through the model and views of the model. There are two ways to produce a viewpoint animation in Autodesk Navisworks:
You can also create slide show animations, which are, essentially, viewpoint transitions with a number of cuts (pauses) added between viewpoints.
In addition to viewpoint animation, you can also animate and interact with 3D geometry in your model. Although the ability to record animations and produce scripts necessary to interact with animated objects is limited to users with access to the Animator and Scripter functionality, any user can actually play them back once they have been recorded.
See Animate Objects for step-by-step instructions on how to record animations and scripts.
