can't open a Rhino 4 3dm file in SW 2014.

Keep getting an error message "does not contain any surface/ solid data". Architect has sent several versions of the file and assures us they are from Rhino 4. We keeps seeing forum references to a Rhino "plug-in", but SW 2014 should open a native 3dm file. Yes?
