I have a dwg that I have attached some time ago to the archicad model file, and subsequently detached it, as I did not need it anymore. Of course now I need it again, and when I try to attach it, Archicad will not allow me. It says that the file name already exists. But when I check in the xref manager, the drawing is not there. It seems like that Archicad remembers the file that I have attached..
Is there a way to have Archicad forgetting the names of the xref files that have been detached?
