Method 1 - Open the drawing in AutoCAD and remove all model space objects:
Open the Inventor DWG in AutoCAD, go to Model Space and delete all model space objects, save the file (then open it in Inventor to verify the model space objects are gone).

Method 2 - Save the drawing as an Inventor IDW then back to an Inventor DWG:
Open the Inventor DWG in Inventor, go to File > Save As and choose 'Inventor Drawing Files (*.idw)' in the file type to save the file as an Inventor IDW, this will remove any AutoCAD Blocks in the file (if you need any of those try Method 1 instead). In the newly saved Inventor IDW, go to File > Save As and choose 'Inventor Drawing Files (*.dwg)' in the file type to save the file as an Inventor DWG file again if required.

Some good methods from Gabriel there. I don't think this browser entry does anything, other than insert your geometry into model space so that AutoCAD can read it as native lines. So it's not necessarily something you need to worry about.
