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.
Both ceiling types can be easily created in Chief Architect.
To create a cathedral ceiling
Open an existing Chief Architect plan in which you would like to create a cathedral ceiling or select File> New Plan from the menu to create a new plan.
Click the Select Objects arrow tool, then click in an empty space of a room that you would like to have a cathedral ceiling to select it.
Note: In order for this method to work, the selected room must have a roof plane built directly above it, rather than a living space on the floor above.
With the room selected, click the Open Object edit button, and on the Structure panel of the Room Specification dialog, uncheck Ceiling Over This Room, then click OK.
To see the results, select 3D> Create Orthographic View> Backclipped Cross Section , then click and drag a camera arrow that runs parallel to the ridge of the roof over the room with the cathedral ceiling.
