EXAMPLE 2: 'DESIGN OF A METAL STRUCTURE' 24 3.2.2 Roof treatment Similarly, from "Edit> " Roofs ", define the type of roof, its orientation and the dimensions Lo,L1,L2,L3, by clicking on and selecting each time with the mouse the 2 ends of the roof in the corresponding direction, viewing the vector in 3D. If your roof has an obstacle (snow accumulation point) select the type of obstacle from the corresponding list and enter its height in m. In the "Geometric Elements" field, enter the number of frames and the remaining geometric elements in m. Rooftop winding up If the structure in question is adjacent to another taller one, in the "Roof adjacency" field select the side that bordering and from from list The field "Roof Coordination" is modified accordingly to enter the necessary geometric characteristics. "OK" to save the parameters. Repeat the process for all four sides of the roof. In the cases of importing metallic structures from Standard Structures, the geometry of the roofs is automatically imported by the program.
