Conical Ceiling

[beton]

How would I create a conical ceiling between the hole in the existing level ceiling and the skylite above.

An In-Place family assigned to the ceiling category. Use the Solid Revolve to define the profile of the cone and revolve it 360 degrees. You'll need to place a reference plane across the center of the opening to use to define the solid revolve profile and axis. You can watch a video HERE (http://www.screencast.com/t/JGqVIZGbbQ).
