But unfortunately the GDL code is referencing to the Archicad 14 and 15 library. Does somebody know where I can download old libraries.<BR /> Thanks</T></DIV> Sun, 16 Apr 2017 18:44:28 GMT https://community.graphisoft.com/t5/Libraries-objects/Where-to-download-old-libraries/m-p/276945#M6731 Anonymous 2017-04-16T18:44:28Z https://community.graphisoft.com/t5/Libraries-objects/Where-to-download-old-libraries/m-p/276946#M6732 Those are migration / legacy references which shouldn't affect creating a new library part in v20 for use in v20.
