Copy a corridor on a new dgn file

I have several corridors in a dgn file.

Another dgn file with the Geometry and another with superelevations are references.

It´s possible copy in a new dgn file one of those corridors , maintaining all rules and without losing  the corridor´s objets?

In other words, How I can copy a corridor and corridors objects in a new dgn file.

Thank you very much.
