  • Add roof edge,
  • Dormer,
  • Join roofs,
  • Opening in roof;
• Construction scope, Window/Recess tab:
  • Roof window;
• Underlay scope, Interpret from IFC file tab:
  • Creates roofs from an IFC file. For more information, see: Interpretation of roofs,
  • Creates windows, doors, and wall openings from an IFC file (to create Roof window);
• Operations related to the creation of Roof during preparation of Building structure:
  • Convert to roof (right mouse button context menu),
  • Automatic walls, slabs and roofs.

Note: In order to view the effects of changes made during editing it is necessary to invoke Computation of building structure .

Location in the program

Construction scope

Icons of tools and functions related to the creation of Roof are accessible in the 2D editor and partly in the 3D view window on the Main tools bar, section Construction when Construction editing is enabled.

3. Roof elements.

4. Roof window.

Underlay scope

Icons of tools and functions related to the creation of Roof and its elements from the IFC file are accessible in 2D editor and 3D view windows on the Main tools bar, section Underlay when Underlay editing is enabled.

5. Create Roof and its elements from IFC file.

Related operations

• Convert to roof operation is available in 2D editor and 3D view windows in the right mouse button context menu. Allows to convert Slab element into Roof.
  

  

  6. Convert to roof.

  
  
• Automatic walls, slabs and roofs operation is available in 2D editor and 3D view windows on the Main tools bar, section Construction when Construction editing is enabled. Allows to automatically generate Roof on the basis of previously created Rooms and Building contour.
  

  

  7. Automatic walls, slabs and roofs.

  
  

Computation of building structure

• Computation of building structure is available on Main tools bar, section Calculations.
  

  

  4. Computation of building structure

  
  

Example of use

1. Create an outline of the roof cover using the Roof component. Then draw the edges of the roof using Add roof edge and specify the elevations of the characteristic points of the roof.
Roof division lines can be deleted by clicking .
Red roof division lines indicate that the division cannot be effected and the elevations of the points or the division lines need to be adjusted.

• shed roof,
  
  
  
• gable roof,
  
  
  
• hip roof,
  
  
  
• half hip roof,
  
  
  
• gambrel roof,
  
  
  
• multifaceted roof.
  
  
  

2. Create a roof with a dormer using Dormer:

• roof with a shed dormer,
  
  
  
• roof with a gabled dormer.
