Description

### 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to have no effect, not even when building parts are exported, so I assume nothing, and it is only a leftover of the outdated cad layer mapping dialog and config file.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?

Research direction

The issue names the IFC Export Classes Mapping and its subcategory level mapping, but no file, test, or entry point. Start by locating that mapping UI and configuration, then trace whether subcategory values affect exported building parts; done means documenting their purpose and side effects or clearly confirming that the mapping is obsolete.
