Editing and Reshaping Roof Faces

● Edit the roof face parameters (such as the angle or eave type) from the Object Info palette.

● Change the roof’s basic 2D object shape using the Edit Roof command. (Be careful not to use the Ungroup command, as this permanently changes the roof face back into the original 2D object.) Use the Exit Roof command to complete the change.

● Change the roof face angle using the Reshape tool (best in Front or Back view).

The roof face properties can be edited from the Object Info palette. The roof face parameters are described in Creating Roof Faces. Only the parameters which are different are described here.

Parameter	Description
Remove Mitered Edges	If the roof face was connected to another roof face with the Connect/Combine tool using Miter Roof Face Joins mode, click to reset the eave to the original Eave Cut (if needed), and reset all other edges to vertical cut geometry
Dormer Settings	When the roof face includes one or more dormers, their parameters can be set. Parameter settings affect all dormers in the roof face.
Wall Thickness	Sets the thickness of the walls in the dormer
Roof Thickness	Sets the thickness of the dormer roof
Style	Displays whether the roof face is styled (with the displayed roof style name) or unstyled, and provides the ability to replace a roof style, edit a roof style, or convert a styled roof to unstyled
Wall Clipping	Indicates whether the roof face is associated with a set of walls, and provides the ability to associate the roof with a set of walls, or disassociate walls from the roof
Components	For unstyled roof faces, opens the Roof Components dialog box to define or edit roof components; see Defining Components for Existing Roofs
Energos	Roofs can participate in Energos energy analysis calculations (see Energos Energy Analysis Module). Vectorworks Architect is required to conduct an energy analysis; however, energy-related parameters can be specified here for informational purposes.
Include in Calculations	When selected, the roof face is eligible to be included in energy calculations, depending on the energy analysis settings for layer/class, element inclusion, and so on.
Boundary Type	Select the type of roof (exterior or foundation). The system list can be modified; see Specifying System Sets. Editing the system parameters, or adding new ones, allows the exterior and interior RS (surface resistance) values to be specified. If the selected boundary roof calculations are not satisfactory, edit the system list to be extremely specific about the roof surface resistance parameters. For a finer level of detail about the boundary roof material, click Advanced. The Advanced Settings dialog box opens. Specify advanced settings. ● Exterior Material: For exterior roofs, indicates the general color of the exterior material. The system list can be modified; see Specifying System Sets. The Absorptivity and Emissivity factors are automatically calculated and displayed. ● Reduction Factor Shading: When the roof is shaded (especially during the summer), enter a shading reduction factor from 0–1, where 0 (zero) indicates total shade and 1 indicates no shade.
Calc R-Value/U-Value	Based on the location of the roof within the building (boundary type) and orientation of the heat flow (surface resistance values), the wall R-Value/U-Value is calculated and displayed. This value, along with the area of the roof, is critical for a correct assessment of the building envelope in energy calculations.
Override Calculated Value	Select this option to override the calculated R-Value/U-Value and enter a manual value for the roof instead in Manual R-Value or Manual U-Value
