[BlenderBIM] Export IFC using BlenderBIM, but only selected objects?

   Hi,

   I was looking at the code shown here:

   "https://wiki.osarch.org/index.php?title=BlenderBIM_Add-on/BlenderBIM_Add-on_code_examples".

   The below code (from the link above) is (I think) supposed to export an ifc but only the selected objects. I guess there has been updates since this example, I am atleast not able to make it work. Does anyone know how to export only the selected objects?

   
   import bpy
   
   import logging
   
   import blenderbim.bim.export_ifc
   
   import blenderbim.bim.qto
   
   settings = blenderbim.bim.export_ifc.IfcExportSettings.factory(bpy.context, '/home/dion/testa.ifc', logging.getLogger('ExportIFC'))
   
   qto_calculator = blenderbim.bim.qto.QtoCalculator()
   
   ifc_parser = blenderbim.bim.export_ifc.IfcParser(settings, qto_calculator)
   
   ifc_exporter = blenderbim.bim.export_ifc.IfcExporter(settings, ifc_parser)
   
   ifc_exporter.export(bpy.context.selected_objects)

   Yeah we don't export anymore, since we now work with IFC natively. What you're looking for is the ExtractElement patch recipe. You can find it in the Blender IFC Debug section:
