HD98545: MEASURE BETWEEN SHOWS WRONG RESULT OF MINIMUM DISTANCE AND ANGLE

APAR status

• Closed as program error.

Error description

• ABSTRACT:
  Measure Between shows wrong result of Minimum distance and
  Angle
  SCENARIO:
  0) Start CATIA.
  1) Open the CATPart. W/B GSD.
  2) Select "Measure Between" icon. "Measure Between" window is
  displayed.
  3) Select "Translate Reference Plane -0.001mm" and "Curve1"
  as selection 1 and 2.
  RESULT:
  The minimum distance and Angle values are displayed. The
  value of Minimum distance is 0.001mm. The value of Angle is
  45.477deg.
  EXPECTED RESULT:
  The result of minimum distance should be 0mm.
  The result of Angle should be 0deg.

  Incident Diagnosis:
  Measure Between shows wrong result of Minimum distance and
  Angle
  Technical explanation of the correction:
  Measure calls the exact operator for getting the minimum
  distance and the exact distance value returned by Exact
  opeartor is actually 0.00099999999992588873 and not 0.001.
  The algorithm of Exact opeartor stops computing any further
  as soon as it finds a distance less than Factory Resolution
  (0.001). This is because anything less than Factory
  Resolution is to be treated as zero distance and there is no
  point refining the result furtherand measure code was just
  rounding off the value to 3 digits i.e., 0.001. But, actually
  it should roundoff to 0 as it is less than the tolerance
  0.001.
  Now, the condition is added to correct the distance value.
  For angle, the value displayed on R20 level is correct and as
  the per the angle computation specification. For details on
  angle computation please refer the documentation: DMU Space
  Analysis > Measure Tools > Measuring Angles
  It seems that the angle 0 deg getting displayed on R18SP5
  level is wrong and considering the scenario the angle cannot
  be 0 deg. The current result is good to observe.
