This is an issue that occurs when I check a drawing into PDM, of an assembly which contains (or I believe EVER contained) and envelope.  In SolidWorks, everything functions as expected in the drawing:

     -The envelope does not appear in any views, except where I check the View Property - "Show Envelope"

     -Where the envelope does appear, it shows with phantom lines

     -All other views appear normal, with solid lines

When I check the drawing into PDM, the issue occurs whereby all of the views which do NOT show the envelope NOW appear in all phantom lines (all parts).
