Problem conclusion

• THIS MODIFICATION WILL BE INCLUDED IN THE
  DOCUMENTATION DELIVERED WITH CATIA VERSION 5 RELEASE
  20 GA LEVEL.
  INCIDENT DIAGNOSIS:
  When Zoom In/OUT are performed, outline is not displayed or
  partially displayed.
  .
  EXPLANATION:
  This behavior is due to Z - fighting phenomenon. The faces are
  drawn with the same vertices than the outlines, and sometimes
  as the Z is equal the faces are drawn and not the outlines.
  As in HRD mode the faces are drawn without any color they
  sometimes hide the outlines. That is why the outlines
  disappear. This problem is not a V5 problem and this cannot
  be corrected.
  .
  BYPASS:
  A by-pass is to modify the line width of the edge to a
  superior
  value. Hence, the faces do not hide the whole line width.
  .
  DOCUMENTATION REFERENCE:
  Infrastructure User's Guide / Basic Tasks Viewing Objects -
  About Stitching (or Z Fighting) Effect.
  .
  This Modification will be added in the R20 Documentation:
  .
  About Stitching (or Z Fighting) Effect titching (also referred
  to
  as "Z fighting") is a visual effect totally independent from
  Version 5 and combines one or more objects on a single one,
  thus giving a pattern looking like stitches.
  .
  When working in HRD mode, a Z fighting effect might occur
  which could result in an incorrect display: depending on the
  zoom, outlines might disappear.
  .
