I am am trying to convert a IFC-file into a CityGML-file. For inspiration I am relying heavily on the intermediate guide for BIM to gis. Now when I am trying to convert the IFCDoors entities into CityGML doors i get the following error:
CityGML Writer: The 'IFMEMultiCurve' geometry is invalid for the 'lod4MultiSurface' citygml_lod_name, valid geometries for 'lod4MultiSurface' are: {IFMEMultiSurface}, convertible geometries are {IFMETriangleFan, IFMEAggregate, IFMECompositeSurface, IFMEFace, IFMEMesh, IFMEDonut, IFMETriangleStrip, IFMERectangleFace, IFMEBox, IFMEBRepSolid, IFMEExtrusion, IFMEMultiSolid, IFMEMultiArea, IFMEEllipse, IFMEPolygon}.

As far as I can tell the error has to do with the fact that some of my IFCDoor objects uses the a MultiCurve for their geometries.
Now for the questions:
Is there any filter that can be used to remove the IFCDoor objects with the IFMEMultiCurve geometry?
Is there any way to transform IFMEMultiCurve geometry to one of the specified valid (or convertible) geometries?
Thanks in advance :D
