How to open ArchiCAD v12 drawing in ArchiCAD v8.1

[Miron]

Dear All,

I got drawing from my friend in AC v12 student version. How can I open it in my v8.1 or how can he export it from v12 to v8.1?

Thanking you.

MM.

By design, student versions are not compatible with professional versions of AC.

I think that a full version will open a Student file but it will switch AC to the Student version and any file opened or created and saved without quitting first will become a student file which is irreversible. You cannot convert a Student File into a Regular File, nor copy-paste information between them.

I don't see any reason to reopen a AC12 student file in a previous version of AC. If you are a student then you can download the AC12 student version also and work on your school project there. If you want to use the student version in an Office Environment then you are violating your license.

What is the reason for opening the AC12 student file in AC8.1?
