Enabling this option sends the created animation as keyframes to the timeline, this could be helpful when you intend to combine multiple animations or modify the animation further.
2-Create animation Sequences
This option will create separate animation sequence for each object, those sequences can then be used in 3D PDF or in VR.
3-Create Reversed Versions
Reversed version of an animation allows the object to go back to its original state, for example, if you have created an animation for a door opening, a reversed version of the door closing will be automatically created.
4-Attach animation Sequences as actions
With this option enabled, the scene is completely ready to be used in a 3D PDF or a VR experience, since all the objects would have their animation attached to them as actions.
