HD98419: GSD: JOIN: ANGULAR THRESHOLD OPTION WORKS FOR LESS THAN 0.5 DEGR EE VALUE

APAR status

• Closed as Permanent restriction.

Error description

• SCENARIO:
  The CATPart contains two surfaces. The angle between two
  surface is 0.2 degree.
  Create Join Of two surfaces with following option.
  Activate Check tangency option
  Activate Angular Threshold option and put 0.3 deg as value
  and Click OK.
  OBSERVATION
  Join is created without error. Angular threshold value is
  particularly useful to avoid joining overlapping elements and
  work on the top of check tangency option. Therefore there is
  no meaning that Angular threshold value can be lower than 0.5
  deg
  .
  EXPECTED RESULT:
  Angular Threshold option should not work for less than 0.5
  degree value and Error message should be displayed. Or it
  should not be possible to set Angular Threshold below 0.5 deg
  

Local fix

• empty

Problem conclusion

• THIS PROBLEM IS PERMANENT RESTRICTION IN CATIA
  Additional Closure Information:
  .
  INCIDENT DIAGNOSIS:
  While using Join command, Angular Threshold option works for
  less than 0.5 degree value even though Check Tangency option
  works till 0.5 degrees.
  .
  RESTRICTION EXPLANATION:
  Check Tangency and Angular threshold options are completely
  different and independent.
  Check tangency option allows checking tangency continuity
  between internal edges (of a surface) as well as merged edges
  (adjacent edges of neighborhood surface) and if angle between
  edges is more than 0.5 degrees, an error is thrown.
  Angular threshold option allows to check that max angle
  between all the adjacent faces of merged cells (faces) is not
  greater than the specified value. This check works on merged
  cells only and does not work on internal edges.
  It is not appropriate to lock/restrict minimum value of
  Angular threshold value to 0.5 degrees because in some other
  cases (especially in Class A surface design) Join command is
  used with less than 0.5deg Angular threshold value. It would
  be seen as a regression for such cases.
  .
  By-Pass: None
