In Autodesk Navisworks there are two types of animation: viewpoint animation and object animation.
Viewpoint animation contains pre-recorded user and camera movements in the model. Object animation contains pre-recorded object movements in the model. You cannot record any animation in Autodesk Navisworks, but you can play back animations saved with the model. If there are any animation scripts, you can switch them on and interact with animated objects.
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.
