HD65113: `CATCREATETOPCLEANCRVOPE? IS SLOWER IN CATIA V5R17.

APAR status

• Closed as suggestion for future release.

Error description

• PROBLEM:
  'CATCreateTopCleanCrvOpe' in CATIAV5R17 is
  slower than in CATIAV5R16.
  .
  SCENARIO on R16:
  01. Compile attached work space under ?R16? by
  CATIAV5R16 and start up CATIA.
  02. Open the attached data
  (XXXXCAD00932_2.CATPart).
  03. Run 'MyTest1'.
  04. Pick the face (First one in the Spec Tree).
  05. Pick the curve (First one in the Spec Tree).
  Then the process time of
  CATCreateTopCleanCrvOpe is saved in
  c:\XXXCAD00932_R16.txt
  .
  06. Continue the step 3,4,5 for other pair of face
  and curve simaltaneously.
  Check the process time for other data.
  .
  SCENARIO on R17:
  01. Compile attached work space under ?R17? by
  CATIAV5R17 and start up CATIA.
  02. Open the attached data
  (XXXXCAD00932_2.CATPart).
  03. Run 'MyTest1'.
  04. Pick the face (First one in the Spec Tree).
  05. Pick the curve (First one in the Spec Tree).
  Then the process time of
  CATCreateTopCleanCrvOpe is saved in
  c:\XXXCAD00932_R17.txt
  .
  06. Continue the step 3,4,5 for other pair of face
  and curve simaltaneously.
  Check the process time for other data.
  .
  RESULT:
  The difference between the work space ?R16
  and ?R17? is only file path of saved text file. But the
  process time of CATCreateTopCleanCrvOpe in
  CATIAV5R17 is about 3 times slower than in
  CATIAV5R16.

  ==========*===========*==========
  THIS APAR IS CONSIDERED AS A SUGGESTION
  FOR IMPROVEMENT WHICH CANNOT BE
  INCORPORATED IN VERSION 5 R18.
  .
  Explanation:
  The performance regression is due to an
  improvement in the shape's result (such as arcs
  number reduction, Comb improved).
  The customer's curves have a huge number of
  arcs, so it's take a long time to know if we can
  suppress them.
  Some works will be done in the next releases to
  improve CPU time, but we can not certify that we
  will retrieve the R16 perfomance in these cases.
  .
  Answer and By-Pass
  Approximate the input curves to reduce the number
  of arcs.
