Convert to dwg

A client came to me with a 3dm Rhino drawing format. It was completed by a designer that we haven’t been able to contact. I have an Autocad file viewer & it does not read this file.

Can someone take my 3dm file and export a dwg file?

Any help would be appreciated.

Thanks,

I could do that.
Or you can install the Rhino demo, it will be good for 25 saves. To convert your file, open the 3dm and SaveAs then select DWG as the file type.
