Starting from a single profile in a Dxf format, WinBuilder finds and creates all the window's cross sections automatically. So, the user needn't to create each solution, coupling frame with sash or mullion, and so on, but WinBuilder does it for him: it put on the plan all the profiles choosed in the order, move them eventually rotating o mirroring them, taking care about the position and the values stored in the archive. All the cross sections created can be saved in a dxf format, compatible with the more used CAD programs.
Printing examples:

• Upper - lateral view
• Cross sections
