First of all, I'm sorry for writting in english, but my German is not good enough.

I'm working with Allplan 2016.

I have problems trying to modify data through .xac files using "Export Object Manager Data" [Objektmanager-Daten exportieren] and "Import Object Manager Data" [Objektmanager-Daten importieren].

Allplan exports correctly the .xac file, I change it and save it in .xac format but when I try to import it nothing happens: I select the correct .xac file but the modified data does not change inside allplan and any message apperars.

I'm doing something wrong?

Thank you very much for your help.
