Disappearance of 2D of Library Objects

Written by László Nagy

In the R3 Patch version of ArchiCAD 8 there is a bug that can cause the 2D of a Library Objects to disappear. Only a dot will be displayed as if the program could not find the Library Object in the loaded libraries.
This will happen only with Library Objects that call macro objects the scripts of which do not contain any GDL commands.
Fortunately, there is only one such Library Object. It is in the German version of ArchiCAD. The name of the Library Object is 'Endelement_1-Fl_2.gsm', and it is a Window Object.
Somewhere in its 2D Script, this Library Object calls the following macro: 'Heizkörpernische.gsm'. This macro is located in the ...Objekt Bibliotheken 84. Makros4.2 Fenster- und Türmakros folder. The 2D Script of this macro is completely empty and this is causing the problem.

The workaround is the following:

1. Open the Macro Library Object 'Heizkörpernische.gsm' for editing.
2. Write the following 2 lines of code into its 2D Script:
   ADDX 1
   DEL 1
3. Save it.
4. Reload the library.
