I have the Archicad 26 in my computer, however, the archive I received is in the Archicad 27 version. Is there a way to save this archive to an older version, so I can open it?
Before the person saves it as Ac26, they should embed all library parts into the file so they can be saved back as well. Otherwise all those Ac27 library parts will be missing from the file as Ac26 will not understand the format.
