Roof Edge Shape

Select the basic shape of this roof edge: Eave, Gable, or Dutch Hip. The default is a hip roof, with an “Eave” edge on all sides. A triangular wall is placed when creating a gable or hip roof.

The available parameters and roof diagram reflect the selected roof edge shape.

Wall Thickness

(Gable and Dutch Hip only)

Specifies the thickness of the wall created for gable and Dutch hip roof edges

Show Wall

(Gable and Dutch Hip only)

Select this option to show the wall created for gable and Dutch hip roof edges; when deselected, the wall is invisible

Gable Overhang

(Dutch Hip only)

Specifies how the gable wall on top of the Dutch hip face will be cut; enter zero for a flat gable wall, or enter the number of inches the gable wall will be inset from the gable roof edge

Gable Inset

(Dutch Hip only)

Specifies how far the gable wall on top of the Dutch hip face will be from the edge of the hip face

Pitch

(Eave and Dutch Hip only)

Specifies the roof pitch as an angle or rise/run ratio; click the calculator for an automatic calculation based on bearing height, eave height, and eave overhang

Bearing Height

Specifies the height of the rafter plate or top plate above the wall layer elevation where the roof will be supported; click the calculator for an automatic calculation based on pitch, eave height, and eave overhang

Eave Height

Specifies the height of the bottom-most portion of the roof; click the calculator for an automatic calculation based on pitch, bearing height, and eave overhang

Eave Overhang

Specifies the distance that the roof extends beyond the bearing wall, click the calculator for an automatic calculation based on pitch, bearing height, and eave height

Hole Cut

(Eave and Dutch Hip only)

Select a hole cut type for this face of the roof, for roof cutouts made with 2D objects (does not apply to holes associated with dormers and skylights).

●        Vertical: Cutout edges are perpendicular to the active layer plane.

●        Splayed: The bottom edge of a cutout is perpendicular to the active layer plane, and the top edge of a cutout is parallel to the active layer plane.

●        Square: Cutout edges are perpendicular to the roof surface.
