I realize that GDL Object Subtypes are based on IFC entities. Because the "Furnishing" Subtype is hardwired into AC, I've created a copy ("Furnishing_OSL") so I can customize the listing parameters.

Does anyone know if changing the name of a Subtype will affect the IFC functionality?

Hi Laura

Sorry it took you so long to receive an answer.

GDL Library Parts are govern by an inertial serial number "GUID" that is composed of 2 parts, the first part tells ArchiCAD what GDL subtype should it reference the new Library Part.

In simple english words for GDL novice: When ArchiCAD reads the object serial number, it will know what type of object it is (ex: door, window, furniture, etc), for more info read GDL guides and manuals

In your case, I guess you have created a new subtype from one that was already available with ArchiCAD, if that was true, then the new subtype that you have created will have a new GUID, but that GUID will reference it parent object, therefore nothing bad will happen.
