Defined in File Ifc4x1.h
This enumeration defines the basic configuration of the window type in terms of the location of window panels. The window configurations are given for windows with one, two or three panels (including fixed panels) as shown in Figure 170. It corresponds to the OperationType of the IfcWindowStyle definition, which references the IfcWindowPanelProperties.
Windows which are subdivided into more than three panels have to be defined by the geometry only. The type of such windows is given by an IfcWindowStyle.OperationType = USERDEFINED or NOTDEFINED (see IfcWindowStyleOperationEnum for details).

The figures are shown as elevations in the XZ plane of the local placement of the window, looking into the direction of the positive Y axis. These figures are only shown as illustrations.
