Imported DGN (microstation) located where?

Successfully read according to Rhino7, but it's impossible to find a file location.

Supposedly named “Original_filename.3dm”, or what? And where?

The open door to Microstation is a very interesting feature in Rhino7. Having worked a lifetime with dgnCAD one can now transfer all of it to Grasshopper/Karamba for structural analysis. Great news!

Sorry for an unnecessary question. The imported file shows up in an already opened Rhino7 file. I just did not see it because of a different miniscule scale.
