Drawing display problems

Hi All,

I have a drawing that is giving me fits.  In the drawing view the detail of the tire is lost and it shows lines that should be hidden behind the tire (see attached TIRE.jpg).  If I change the view to an isometric or trimetric view it shows up correctly (see attached TIRE2.jpg).  When I go back to the front view it shows up correctly for a split second then goes back to looking like the TIRE.jpg.  I have tried turning off "Large Assembly Mode" and changing the image quality in the document options, nothing seems to change it.

I know that this worked in SW2007 from the old copies of the drawings.

Does anyone have any ideas on what to change?  I would appreciate any help.

Thanks,

Jody
