Right now I do not see an option to IMPORT .3dm Rhino files into eDrawings Viewer ... we do have the option of other type of files like .dwg. .dxf. STEP, .stl .... and others ... but there is no way to IMPORT Rhino Files.

IT WOULD BE GOOD THAT eDrawings Viewer ADD THIS OPTION TO THE LIST OF TYPE OF FILES TO OPEN OR IMPORT to view ... 

Thank You
