Hi,
The IFC Exporter Plugin has been integrated so it much more adaptable.
First configure your mapping table: Revit Category - IFC Class by: Revit--> Export--> Options --> IFC Options
Consider this list since Revit does not support all IFC Classes
Sometimes this does not work or if you have nested families where individual parts need to be exported into different classes you can use the IfcExportAs Parameter:
Create a shared Parameter as Text and name it "IfcExportAs" and group it under IFC Parameters. you can set it up as type or as Instance, depending your needs.
I prefer to use "Type" so i put in the IFC Class directely inside the family and the users do not have to worry about it.
Does this help? If you have questions, let me know.
good luck
