First, I have exploded, purge, flatten, and cleaned everything in my autocad file before exporting.
I have exported my file into different versions of Autocad from the latest 2013 to the 2000 version. In all of them I keep getting the same error when I try to import it in Rhino:
Opened AutoCAD file version Unknown.
Error converting file.
Am I missing a step before importing to Rhino?
I have tried importing the dwg file from Vectorworks and Exporting it again into all versions of Autocad but still the same problem.
My Rhino version in mac: 5.1 (5B161)
Mac: Yosemite 10.10.5
