The DXF button allows to export the wind rose as CAD DXF files that can be loaded, for example, in AutoCAD (Autodesk, Inc.). Note than only wind roses can be exported in DXF format, not other types of plot.
The DXF file can be exported in any existing directory selected by the user and with any name.
The DXF file is produced according to versions R11/R12 and should be readable from all the new versions.
An example of image obtained importing in AutoCAD (Autodesk, Inc) a DXF produced with WindRose Pro is shown below.
