HD06420: CATDYNMASSPROPERTIES1D::GETPARAMFROMLENGTH() DOES NOT WORK CORR ECT (SINCE R10 SP2 OR SP3)

APAR status

• Closed as program error.

Error description

• Description:
  In the Following code sequence, Length1 and
  Length2 should be the same but it isn't. This bug is
  new from R10SP2 or SP3, because our tests on
  SP1 brought the correct result.
  
  // ----------- Begin of code -----------------
  CATEdgeCurve *pEdgeCrv = hEdge->GetCurve( );
  CATCurve *pCrv = pEdgeCrv->GetRefCurve();
  
  CATCrvParam ioStartParam;
  CATCrvParam ioEndParam;
  hEdge->GetVerticesParamsOnEdgeCurve (
  &ioStartParam, &ioEndParam );
  
  CATDynMassProperties1D *pDynMassOpe1D =
  CATDynCreateMassProperties1D ( pCrv );
  double Length1 = pDynMassOpe1D-
  >GetLengthFromParams ( ioStartParam,
  ioEndParam );
  .
  CATCrvParam Parameter = pDynMassOpe1D-
  >GetParamFromLength ( ioStartParam, Length1 );
  double Length2 = pDynMassOpe1D-
  >GetLengthFromParams ( ioStartParam,
  Parameter );
  cout << "L1:" << Length1 << endl;
  cout << "L2:" << Length2 << endl;
  
  cout << "P3:" << Parameter << endl;
  // ----------- End of code -----------------
  
  SCENARIO:
  - Build the command using the provided Workspace,
  - Launch CATIA,
  - Open the provided CATPart,
  - Go to Part Design Workbench,
  - Select 'Bug' command,
  - Select the line (see .jpg file),
  ==> observe console: L1 and L2 are not identical
  although they were on V5R10 SP01.
