Description
The Roof tool allows you to create a sloped roof from a selected wire. The created roof object is parametric, keeping its relationship with the base object. The principle is that each edge is seen allotting a profile of roof (slope, width, overhang, thickness).
This tool is still in development, and might fail with very complex shapes.

How to use
- Create a wire with following the counterclockwise direction and select it.
- Press the
Arch Roof button, or press R then F keys
- The default roof object could have a strange shape, it's because the tool have not all the needed informations.
- After creating the default roof, double click on the object in the tree view to access and edit all the properties. Angle must be between 0 and 90.
- Each line correspond to a roof pane. So you can set properties you want for each roof pane.
- To help you, you can set Angle or Run to 0 and defined a Relative Id, this make automatic calculs to find the data relative to the relative Id.
- It work like this :
- If Angle = 0 and Run = 0 then profile is identical to the relative profile.
- If Angle = 0 then angle is calculated so that the height is the same one as the relative profile.
- If Run = 0 then Run is calculated so that the height is the same one as the relative profile.
- At the end, set an angle to 90° to make a gable.

Options
- Roofs share the common properties and behaviours of all Arch Components
Properties
- DataAngles: List of the slope angle of the roof pane (an angle for each edge in the wire).
- DataRuns: List of the width of the roof pane (a run for each edge in the wire).
- DataIdRel: List of relation Id The slope angle of the roof
- DataThickness: List of thickness of the roof pane. (a thickness for each edge in the wire).
- DataOverhang: List of the overhang of the roof pane (an overhang for each edge in the wire).
- DataFace: The face index of the base object to be used #Not really used
Scripting
See also: Arch API and FreeCAD Scripting Basics.
The Roof tool can be used in macros and from the Python console by using the following function:
Roof = makeRoof(baseobj=None, facenr=0, angles=[45.,], run=[], idrel=[0,], thickness=[50.,], overhang=[100.,], name="Roof")
- Creates a
Roof
object from the givenbaseobj
, which can be a closed wire or a solid object.- If
baseobj
is a wire, you can provide lists forangles
,run
,idrel
,thickness
, andoverhang
, for each edge in the wire to define the shape of the roof. - The lists are automatically completed to match the number of edges in the wire.
- If
Example:
import FreeCAD, Arch, Draft
Rect = Draft.makeRectangle(3000, 4000)
Roof = Arch.makeRoof(Rect, angles=[30.,])
FreeCAD.ActiveDocument.recompute()
p1 = FreeCAD.Vector(0, 0, 0)
p2 = FreeCAD.Vector(1000, 1000, 0)
p3 = FreeCAD.Vector(0, 2000, 0)
Wire = Draft.makeWire([p1, p2, p3], closed=True)
Roof2 = Arch.makeRoof(Wire)
