Floor and Ceiling Trusses

Floor and ceiling trusses can be used instead of joists to frame platforms. As with manually-drawn floor and ceiling framing, the room type above determines whether a floor or ceiling truss is drawn. For example, a truss drawn on the first floor of a single story home will be a ceiling truss, while a truss drawn on the first floor of a two-story building will be a floor truss for the 2nd floor.

To place a floor or ceiling truss in your plan, select Build> Framing> Floor/Ceiling Truss . Click and drag to create a truss in floor plan view.

Roof trusses seek an exterior wall and adjust their length automatically. Floor trusses do not, but if you start or end your truss close to a wall surface or CAD object, the truss snaps to the surface or object.

The Trusses tab of the Build Framing dialog contains default settings for floor and ceiling trusses. See "Trusses Tab". These default settings can be overridden by the settings in the Floor/Ceiling Truss Specification dialog. See "Floor/Ceiling Truss Specification Dialog".
