Hi there,

Few days ago, I have found these two GDL integer parameters "ifc_subtype" & "ifc_predefinedtype" that were found in ArchiCAD's standard MEP Library Parts. And the "GDL Reference Manual" textually mentions that the "ifc_subtype" is one of those parameters that the Add-ons get the values it needs from the library part.

So my question is, what takes preference when exporting the project through the IFC Project Manager, would be those predefined parameters in project's library parts, or the properties that have been mapped to them ?
