Need help Importing Autocad >DWG files

I am using Autodesk Inventor R4 and when I try importing the Drill Motor Transmission Mount Autocad .DWG into a drawing file
I get a blank drawing. Can anyone help??

heres what you do…

if the autocad drawing is a 3d model:

open inventor…

goto the add-in manager and turn on dwg

then make a new part and import in the dwg solid.

THen you can make a new idw with the model in inventor

OK?? the add-in manager does not list dwg to turn on
It has DSS Monitor Add-in and Fasteners listed
