Define slope for middle boundary line and write in Offset From Roof Base parameter.Ĥ. For a half hip gable end – split entire line into three and remove slope definition for two side boundary lines.ģ. Create roof with slope definition for all three external boundary lines.Ģ. To create a hip dormer roof or a half hip roof, create roof by footprint as in previous examples and follow these steps.ġ. To create a roof sweep, add roof by footprint and remove slope definition from inner boundary lines. Cut roof openings as in previous example.ġ4. For remaining mono pitches repeat same process, and either use a slope arrow or add a slope to one of the perimeter roof boundary lines. For mono pitch dormers repeat the process, but remove slope definition and instead add a slope arrow, which can be further defined in properties.ġ3. Pick roof/wall edges and trim corners of model lines.ġ2. Use Join/Unjoin Roof function in Geometry tab and select both main roof and dormer roof – then create a dormer opening for the main roof. To make a double pitch dormer roof, create roof by footprint at corresponding level, untick slope parameter for gable end boundary line, connect corners, draw a new line at the back and switch off slope parameter, and attach gable end wall to roof.ġ1. You can also create walls at the relevant attic level and attach them.ġ0. Select walls from lower levels and attach to roof. Rafter Cut type, Slope and Constraint parameters can be changed.ĩ. Remove slopes where gable ends are desired (untick ‘define slopes’).Ĩ. Add slope arrows for each boundary line pointing to each other.ħ. For triangular dormers add one boundary line for each slope of dormer.ĥ. Add roof by footprint by selecting external walls.Ĥ. Prepare walls and levels for entire house.ģ. Roof pitches can be manually adjusted using grab handles.Ģ. To achieve these more complex shapes, again, follow the steps given in the first example and adjust some settings.ġ. In the next example we will see how dormers, mono pitches, and double-pitch gable end roof types can be modeled using the ‘Roof by Footprint’ function. Select multiple walls and use Attach Top/Base function. Wall can be attached to follow roof line.Ĥ. Define overhangs and switch off slope parameter for gable end roof boundary lines.ģ. Roof slope may be adjusted using grab handles.įor a different variation of a hip roof, follow the same steps given above and adjust a few parameters as shown below.ġ. Each boundary line can be edited individually.Ĥ.
