Our graphics department requires vector line art for packaging and instruction manuals.  This is an easy thing to do by saving the part as a DWG file and opening in Illustrator.  However assemblies will not save to a DWG file and to overcome this:

1.  Save assembly as an IGES file.

2.  Open IGES file in SW and save as a SW part.

3.  Open SW part file and save as an DWG file.  Note:  When the assembled part is open and before saving as a DWG, you may add perspective or camera view.  These view(s) are saved when the assembled part is saved as a DWG. 

4.  Open DWG file in Illustrator and edit (remove) tangent lines as needed.
