Roof by Extrusion
This method is best applied for roof shapes that are generated by extrusion of a profile, such as saw-tooth roofs, barrel vaults, and waveform roofs. Like the by footprint method, it is based on a sketch; however, the sketch that defines the shape of the roof is drawn in elevation/section view (not in plan view) and is then extruded along the plan of the building (Figure 11.38).

The Roof By Extrusion tool offers additional settings in the Options bar when selected Roofs by extrusion do not have an option to follow the building footprint, but that is often needed to complete the design. To accommodate this, use the Cut Plan Profile tool, available only when Roof by Extrusion is selected. Briefly, you create your roof by extrusion by defining a profile in elevation that is then extruded above the building. The extrusion is along a straight path, which is not necessarily the same as to the building footprint. If the shape of the building is nonrectangular in footprint or the shape of the roof is not regular, the use of this tool allows you to shape the roof profile to match the footprint. Recall that with sketch-based design, any closed loop of lines creates a positive shape, every next loop inside it is negative, and so on. In Figure 11.39, a roof by extrusion is drawn at an angle to the walls. To clip the roof to meet the walls, the Cut Plan Profile tool is used to draw a negative shape.
