Problem conclusion

• THIS PROBLEM IS PERMANENT RESTRICTION IN
  CATIA
  INCIDENT DIAGNOSIS
  Tool shape is created partially with Create
  Geometry function due to self intersecting
  geometry.
  RESTRICTION EXPLANATION
  In the Create Geometry command, the tool
  Geometries are created using the revolution
  surface operator.
  .
  The profile of the tool contains an edge whose
  length is equal to the geometric tolerance (0.001
  mm = 1 micron).
  .
  The revolution surface operator considers such a
  profile as self intersecting.
  .
  In such cases the creation of the revolution surface
  operator is not guaranteed. Hence the tool
  geometry gets created at some locations while at
  others it does not create.
  By-Pass
  .
  If the tool profile is such that the length of the
  edge is larger than the geometric tolerance (> 1
  micron), the revolution surface operator will work
  correctly. This can be achieved by increasing the
  value of db from 0.5 mm to 0.502 mm.
  .
