HD61504: GSD: JOIN: ERROR WITH SELF INTERSECTING FACES

APAR status

• Closed as Permanent restriction.

Error description

• GSD: JOIN: ERROR WITH SELF INTERSECTING
  FACES
  .
  SCENARIO:
  1) Start CATIA.
  2) Open
  70369.001.866_070205164213_Three_Corner_Fillet
  _Join_Error.CATPart.
  = The surfaces within the part have been color
  coded for this scenario.
  = There are two geometrical sets, each holding
  different geometry which both represents the
  problem.
  3) Using surfaces from GS - Overlap issue 1:
  Join - Pink + Green + Yellow = Error
  Join - Purple + Pink + Green + Yellow = OK
  Join - Yellow + Blue = Error
  4) Using surfaces from GS Overlap issue 2
  Join - Pink + Green = OK
  Join - Pink + Green + Purple = Error
  Join - Pink + Green + Purple + Yellow = OK
  Join - Purple + Blue = Error.
  .
  OBSERVATION:
  Error is displayed and Join is not possible:
  "Join operation aborted on invalid elements.
  Input elements surface.1 has several self-
  intersecting edges.
  Modify these inputs or the elements used to
  generate them".
  .

Problem conclusion

• THIS PROBLEM IS PERMANENT RESTRICTION IN
  CATIA
  .
  Incident Diagnosis:
  The problem is related to the fact that the surfaces
  contain confused edges. Due to this the body is not
  valid.
  .
  Restriction Explanation:
  Overlap issue 1 - Yellow has 2 confused edges,
  which is invalid. When a body is invalid, the
  behaviour of the operator is random.
  Similar is the case with Overlap issue 2.
  .
  By-Pass:
  Overlap issue 1 (similarly 2) : Eliminate the smallest
  edge of Yellow (similarly Purple).
  (Refer attached data)
