HD19647: GSD / EDGE FILLET : FILLET CANNOT BE CREATED AFTER CHANGE IN SP LIT

APAR status

• Closed as Permanent restriction.

Error description

• GSD / EDGE FILLET : FILLET CANNOT BE CREATED
  AFTER CHANGE IN SPLIT
  .
  This problem is reproducible in R14 latest level.
  .
  When split is edited and other side is clicked twice,
  update error occurs for Edge Fillet. User can not
  make edge fillet with R=70mm (or after updating
  model), but user can make the fillet after
  previewing with R=60mm.

Problem conclusion

• THIS PROBLEM IS PERMANENT RESTRICTION IN
  CATIA
  .
  Incident Diagnosis:
  PROBLEM1: Fillet.1 70mm impossible.
  PROBLEM2: Fillet.1 70mm possible after preview
  with 60mm.
  .
  Restriction Explanation:
  PROBLEM1:
  Earlier CGM operators were allowed to extrapolate
  input surfaces as much as needed. As a
  consequence, the customer had a problem because
  the model size increased due to huge surfaces,
  many times extrapolated. We do not want to
  extrapolate automatically the surfaces without user
  interaction. See attached PPT. This is to avoid
  growing of data size. The user has to explicitly
  extrapolate. Closure of this problem is PRS.
  .
  As the CATPart is read as it is, surfaces are widely
  extrapolated because of previous operators. Thus
  fillet can be created because it does not have to
  extrapolate the surfaces, it can found on the
  existing surface an area where the Sphere touches
  both surfaces.
  .
  If split is modified, then CATPart is updated, all the
  operators are run again and now do not
  extrapolate the surfaces (this modification should
  have been versioned but it was not in order to
  allow the customers to reduce the model size of
  their parts just by running an update). So when the
  fillet is run, the surface are have not been
  previously extrapolated and it does not find any
  area where the sphere touches both surfaces, and
  it fails. This is an unwanted side effect of an overall
  improvement regarding model size.
  .
  PROBLEM2: It has been fixed since R13. Preview
  with 60mm radius does not allow any more the
  70mm fillet to be OK.
  .
  By-Pass
  Extrapolate the surface.
