Animations

On the Project tab, click Options, click Views, click Animations to allow the toggle smooth pan and zoom operations in 3D View when the Zoom To and Walk To options are used. The zoom operation is animated to show the transition from the original view definition to the final view definition.

Note:
Animations only operates if the system determines that the hardware is capable of performing a smooth pan and zoom with the size of model displayed in the 3D View.
