[QGIS-Developer] How to save a DXF 3D using pyQgis ?

[Geo DrinX]

Good evening to all,

as in object,  there is a way to save a DXF from a 3D polygon layer, using
pyQgis ?

I am using:

QgsVectorFileWriter.writeAsVectorFormat(layer, file, "UTF-8", crsCrs,
"DXF", overrideGeometryType=QgsWkbTypes.PolygonZ,skipAttributeCreation=True)

but (also it works with other file types) the option "overrideGeometryType"
seems to be irrilevant with DXF, and it saves in 2D.

Someone can help me to discover the correct syntax ?

Thank you in advance

Roberto
