HE00927: PART : PAD : INCONSISTENT BEHAVIOR OF PAD COMMAND WHEN PROFILE I S SELF-INTERSECTING.

APAR status

• Closed as Permanent restriction.

Error description

• SCENARIO:
  1. Start CATIA V5
  2. Create a new CATPart
  CASE 1:
  3. Go into sketcher workbench and create a profile with
  following co-ordinates on XY plane.
  4. Select Profile icon and create a sketch using points at
  following co-ordinates
  Point 1 at (0, 0)
  Point 2 at (40, 0)
  Point 3 at (40, 40)
  Point 4 at (0, 40)
  Point 5 at (0, -10)
  5. Click Exit workbench
  6. Select Pad command
  7. Select the sketch (created at step 3 to 5)
  8. Click Ok
  Observation:
  Feature Definition Error
  You must use thick option in order to use an open profile,
  whenever current feature is the first solid feature of a
  body. Do you want to use the selected sketch anyway?
  9. Click Yes on error and click OK in Pad dialog box
  Observation:
  Update Error
  Part1\PartBody\Pad.1
  You must use thick option in order to use an open profile,
  whenever current feature is the first solid feature of a body
  This is correct behavior.
  .
  CASE 2
  9. Double click on sketch.1 to go into the sketch
  10. Create a line starting from (0, 0) to (0, -10) so that it
  will overlap the earlier line and select exit workbench.
  11.  Select Pad command
  12. Select the sketch
  13. Click Ok
  Observation:
  No error appears and Pad is created.-This is a problem.
  .
  PROBLEM:
  Inconsistent behavior of Pad command when profile is
  self-intersecting.
  EXPECTED RESULT:
  Behavior of Pad should be consistent and error should appear
  in both the cases.

Problem conclusion

• THIS PROBLEM IS PERMANENT RESTRICTION IN CATIA
  Additional Closure Information:
  .
  INCIDENT DIAGNOSIS:
  Inconsistent behavior of Pad command when profile is
  self-intersecting.
  .
  RESTRICTION EXPLANATION:
  When user creates additional overlapping line, the earlier
  open profile(sketch) gets closed. Then this closed sketch is
  taken as input for the Pad. Pad algorithm uses the clever
  computation by healing the edge (overlapping line) which is
  self crossed. Thus the Pad is created using the healed face
  which is correct behavior. It is not appropriate to restrict
  Pad creation and throwing an error message as profile itself
  is closed.  Furthermore it will introduce the regression in
  the other parts which are created using the healed sketches.
  .
  By-Pass:
  None
