  SCENARIO:
  0) Start CATIA V5R16GA.
  1) Open the attached CATPart'.
  Workbench : 'GSD'.
  2) Click 'Join' icon.
  => 'Join Definition' panel is displayed.

  4) Uncheck 'Check connexity'.
  5) Click 'OK'.
  =>'Update Error' panel is displayed.
  =>'Tangency Error' is displayed on 'Suface4'

  in Geometry Area.
  6) Click 'OK' in 'Update Error' panel.
  => 'Join Definition' panel is displayed,again.
  7) Click 'Remove Mode'.
  8) Select one Surface from Geometry Area.< (Any
  surface is ok.)
  This case select 'Surface.1'.
  =>'Surface.2' - 'Surface.5' are selected as
  Elements to Join.
  9) Click 'OK'.
  =>'Join.1' is created.<.
  < RESULT >
  -'Join' cannot be created with 'Tangency Error',
  if all 'Surface' are selected.
  -'Join' can be created even if it deletes surface
  which is unrelated to a 'Tangency Error'.
  .
  < RESULT TO EXPECT >
  'Join' should be created if all 'Surface' are selected.
  .
  < Remarks >
  -If expansion 'Surface.4' and 'Surface.5',It seems
  to cross.

Problem conclusion

• THIS PROBLEM WILL BE FIXED ON CATIA VERSION
  5 RELEASE 17 GA level.
  .
  Incident Diagnosis
  The error message of the Join is not clear enough.
  .
  Correction Explanation
  A new error message has been delivered to help
  the user to understand the problem.
  The new message is :
  Join operator:
  Some edges haven't been merged, although they
  are closer than resolution, because skin will be
  unorientable.
  They may come from faces overlap. Modify
  adjacent faces in order to suppress these overlaps.
