Use the
Library Manager to put the objects in an
Embedded Library, Save As... that .pln file with the Embedded Library as an ArchiCAD 14 project file, open that file in ArchiCAD 14, then use the Library Manager to
Export the library parts. The parts will then be AC 14 format, but any commands new to AC 15 will not translate to AC 14.
