Objects that are not part of the ArchiCAD Library should not be placed in the ArchiCAD Library as they will get deleted when the ArchiCAD Library is updated or if the application needs to be reinstalled. If the objects are for just one project, put them in that project's Embedded Library, otherwise create a new folder for these extra objects and load that library in addition to the ArchiCAD Library.
You should add a Signature to your Profile (click the Profile button near the top of this page) with your ArchiCAD version and operating system (see mine for an example) for more accurate help in this forum.
