The Help is a good place to start, particularly the "Search" option where you can type in the term you want more information on and search for it. (Although searching "Elevation: Top" in this case is not so useful.)
You should add a Signature to your Profile (click the Profile button near the top of this page) with your ArchiCAD version and operating system (see mine for an example) for more accurate help in this forum.
