This is the default IFC export settings used if no IFC class is specified on the family type.
However in just using these default settings you cant use different IFC types within the same category.
So we recommend using the parameter "IFCExportAs" on family types to specify the IFC class.
Doing so will give you a lot more flexibility.
For example "Electrical Equipment" familys often needs to export to different IFC classes.
You can only do that by using "IFCExportAs" in Element Properties.
