Which ones are available, depends on the kind of window.
With format EP2 it is possible to export contents of the 2D window (for example in the cross-sections database manager).
Format EP3 can be used for export from a 3D window (normal SCIA Engineer graphical window, gallery, etc.).
Format EPD is a window of a paperspace. All formats can be inserted to a paperspace with keeping the original sense, that's a main reason of existence of those formats. (for example EP3 works as fully 3D on paperspace, including lateral change of view direction, hidden lines removal etc.).
