I want to create a room with a cathedral ceiling. How do I do this?
When a room's ceiling is pitched rather than flat it is referred to as either a cathedral or vaulted ceiling. Cathedral ceilings are the same pitch as the roof and are typically produced by enclosing the bottoms of the roof rafters with a ceiling material.
Vaulted ceilings, while similar, do not share the same pitch as the roof, and are often framed using scissor trusses. If you are interested in a Vaulted Ceiling rather than a Cathedral, please see the Related Articles section below.
In X15, an edit tool called "Turn Off Ceiling" was introduced. This tool allows you to easily, and quickly, remove the flat ceiling in a selected room without the need to open the Room Specification dialog.
