we use a Library Element as a kind of BIM-Messenger.
There fore we create an custom-attribute under a chapter Messenger (see attachments Messenger.Untertitel, Messenger.Wert1, Messenger.Wert2), see attachments -> they are assigned to IFC Properties (IFC.Zusatz.Untertitel etc.)
The question is, how can we can we access these custom attributes in a GDL script and how is the connotation?
Something like REQUEST(“Messenger.Untertitel”, “”, Title) or REQUEST(“IFC.ZUSATZ.Untertitel”, “”, Title)?
I would be grateful for some hints, or an example.
