The Play button plays the animation in the active viewport. If you click another viewport to make it active, the animation continues playing in that viewport. When the animation is playing, the Play button becomes a Stop button. The Play button is a flyout for playing only the animation of selected objects.
Tip: You can play the animation in all the viewports simultaneously by turning off Active Viewport Only in the Time Configuration dialog.
To play the animation in the viewport:
The Play/Stop flyout contains two buttons. Both buttons become a Stop button when in use.
Play—Plays the animation in the currently active viewport.
Play Selected—Plays the animation for selected objects only in the currently active viewport.
Stop Animation—Replaces the Play button when an animation is playing. Click to stop the playback.
Stop Animation (Selected)—Replaces the Play Selected button when an animation is playing. Click to stop the playback.
