trying to open a model from 2012/13 to work on a new project on the site......see above plan, plus screenshot of missing parts. I assume that these are from library would be related to version 12, but where is this library which was once accessible? Can I recover the library? Is it on my machine or perhaps on the original version 12 disc? OR do I have to remodel each door/window from photographic records?
AC always include previous versions of Libraries in order to migrate the files.
When you open an old file AC should ask to migrate the project and it should add the correct libraries to show all elements.
If you didn't migrate it the first time AC should ask you again on reopening.
If it didn't then you can link the missing libraries by opening "Library Manager", selecting "ADD" and going to your AC's installation Folder (location depends on OS) and looking under "Archicad Migration Libraries" and/or "Archicad Migration Libraries Old".
The only reason this might not work is if the file was created with a different "flavor" of AC, ie original file was INT and you are using USA version of AC
