   Figure: QElectroTech polygon part from element

QElectroTech allows customizing different polygon properties:

:Appearence:

    :Color:

        The outline and filling color of the part can be defined from a list of 
        pre-defined colors. At the case of an open polygon part the filling color is **None**.

    :Style:

        The outline representation type can be chosen between: Normal 
        (Continuous), Dashed, Dotted or, Dots and dashes. 

    :Thickness:

        The outline thickness (Weight) can be chosen between: None, Thin, Normal, Strong 
        or High.

:Geometry:

    :Type of polygon:

        QElectroTech has two different types of polygons, open polygon which is assimilated to a 
        group of connected lines and close polygon which is assimilated to closed geometry as the 
        rectangle.
    
    :Coordenates:

        The polygon points coordinates (x, y) can be defined and storaged in a list.
