I'm trying to take a simple shapefile and transform it to citygml. I've found a couple solutions that suggest all I need is what it defined in my attached workspace but the output doesn't seem to honor my extruded geometry. Any ideas what I'm doing wrong?
And here is a picture of the workspace if that helps.


When I open the citygml file into QGIS, it looks like this where all the geometry is at the south pole.
