I have created a cathedral ceiling in my drawing, but I cannot figure out how to assign a new or different material to the ceiling. How is this accomplished?


A cathedral ceiling can be created by removing the ceiling of a building or room, forcing the ceiling surface to generate on the underside of the roof planes.

Use the procedure below to change the ceiling material for a cathedral ceiling.

For the purposes of this tutorial, we will start the process of creating a structure with a cathedral ceiling, and then change the materials for the cathedral ceiling, from the very beginning.

To create a cathedral ceiling

  1. To create a cathedral ceiling, use the Select Objects tool to select a room, then click on the Open Object edit tool to display the Room Specification dialog.

  2. On the Structure panel, uncheck the check box beside Ceiling Over This Room.

  3. On the Materials panel:

    • Select Ceiling Finish.

    • Click the Select Material button to display the Select Material dialog.

    • Browse and select an appropriate material and click OK.

  4. Click OK to return to plan view.
