Hide Lock and Attach Objects
Use the hide, attach and lock features to further edit your objects and make them flow seamlessly with your movie.
Hide, lock and attach objects in the Timeline Helper which is the panel to the right of the scene in Design view, if the panel is not there go to View and click on Timeline Helper. The icons at the top of this panel are:
Transformations which will show you the changes you have made to your scene, Objects which will show you a list of the objects you have added to your scene and Marks which shows where you have bookmarked your scene.
Select Objects, next to each object there are 3 options for it. The first dot will show or hide you object. The second dot will attach an object to the background, so if you have rotated the background the object will now rotate to fit it. The last icon will lock your object so that it cannot be moved or edited.
