Export game level to file?

Is it possible to export a game level that I create in Unity’s editor to a file so that I can import it into 3D modeling program?

It’s certainly possible but you will need to write a script that does it.

Is there anything on the Asset Store that lets me export a game level that I create in Unity’s editor to a file so that I can import it into 3D modeling program? A few add-ons lets you export one 3D mesh to files.
