Creating Roof Objects

To create a roof object:

1. Select the walls, polygon, or polyline that the roof will be based upon.

Shift-click to select multiple walls. If the building has an attachment, such as a garage, that will have a different roof structure, then select only the desired walls.

When the roof object is based on walls, the walls are automatically associated with the roof when determining component display (Vectorworks Design Series required).

2. Select the Create Roof command from the appropriate menu.

●    Fundamentals workspace: Model > AEC > Create Roof

●    Architect workspace: AEC > Create Roof

●    Landmark workspace: Landmark > Architectural > Create Roof

●    Spotlight workspace: Spotlight > Architectural > Create Roof

The Create Roof dialog box opens. Enter the desired criteria to create the roof object. The parameters are illustrated in the roof diagram. Certain default parameters are suggested based on the selected roof parameters.

Click to show/hide the parameters.

Parameter	Description
Eave Profile	Select the roof edge appearance ●    Square: angled fascia, soffit edges ●    Vertical: vertical fascia, angled soffit edges ●    Horizontal: no fascia, horizontal soffit edges ●    Double: vertical fascia, horizontal soffit edges
(1) Vertical	Specifies the vertical length for a double miter eave
(2) Horizontal	Specifies the horizontal length for a double miter eave
(3) Thickness	Specifies the roof thickness; when the roof face is styled (Vectorworks Design Series required), this parameter is not available since the components determine the thickness
(4) Bearing Inset	Specifies how far the bearing wall cuts into the roof
(5) Roof Pitch	Specifies the roof pitch as an angle or rise:run ratio; click Calculate for an automatic calculation based on bearing height, eave height, and eave overhang
(6) Bearing Height	Specifies the height of the rafter plate or top plate above the wall layer elevation where the roof will be supported; click Calculate for an automatic calculation based on roof pitch, eave height, and eave overhang
(7) Eave Height	Specifies the height of the lowest portion of the roof; click Calculate for an automatic calculation based on roof pitch, bearing height, and eave overhang
(8) Eave Overhang	Specifies the distance that the roof extends beyond the bearing wall; click Calculate for an automatic calculation based on roof pitch, bearing height, and eave height
Layer	Assigns the roof object to a layer. By default, the roof is created in the active design layer. To create the roof in a different layer, select an existing layer from the list, or select New Layer to create a new layer.
Class	Assigns the roof object to a class. The standard roof class, Roof-Main, is available as an option and if it is selected, it is created in the file if it did not already exist. Alternatively, select Class to create a new class.
Style (Design Series required)	Select a roof style, or open the Roof Preferences dialog box for creating or editing a roof style. See Using Roof Styles.
Create Accessories (Architect required)	Adds an attic, soffit, or fascia to the roof object; see Adding Roof Accessories
Retain Original Objects	Retains the source objects that formed the basis of the roof

3. Click OK.

A hip roof is created over the selected objects using the criteria set in the Create Roof dialog box. The roof can be changed to a gable or Dutch hip shape; see Changing the Roof Edge Shape.
