INQ: Subcategory Mapping

[thumDer]

Inquiry description

What is the purpose of subcategory level mapping of ifc classes in the IFC Export Classes Mapping?It seems to have no effect, not even when building parts are exported, so I assume nothing, and it is only a leftover of the outdated cad layer mapping dialog and config file. This is totally confusing. Do they have any sideeffects?
