HD79654: GSD: TANGENT INTERSECTION EDGES IN EDGEFILLET ARE UPDATED AFTER RECREATING GEOMETRY IN THE SKETCH.

APAR status

• Closed as Permanent restriction.

Error description

• SCENARIO:
  1. Start CATIA V5
  2. Open CATPart W/B GSD.
  3. Expand tree of "Part Body".
  4. Click "Edge Fillet" command.
  "Edge Fillet Definition" window is displayed.
  5. Select Edge of ThickSurface.1.
  Key-in 2mm as "Radius".
  Select "Intersection" as "Propagation".
  6. Click "OK".
  "EdgeFillet.1" is created.
  7. Double Click "Sketch.1" in tree.
  "Sketcher" W/B is started.
  8. Delete "Line.6" and recreate a new line with
  tangency to "Circle.1".
  9. Exit "Sketcher" W/B.
  .
  OBSERVATION 1:
  "Update Diagnosis" error is displayed
  on "EdgeFillet.1".
  Error message:
  Edges or face not found
  Re-select the edge or face on current geometry.
  .
  10. Close the message and delete the fillet created.
  11. Perform steps 4-6. again
  12. Upgrade the new edge fillet created.
  11. Perform steps 7- 9.
  .
  OBSERVATION 2:
  Update error is not displayed.
  Automatic reroute operation is performed correctly
  and the fillet is ok.
  Although feature created release and upgraded
  release are same, the behavior is different.

Problem conclusion

• THIS PROBLEM IS PERMANENT RESTRICTION IN
  CATIA
  INCIDENT DIAGNOSIS:
  Tangent intersection edges in edge fillet are
  updated after recreating geometry in the sketch.
  .
  RESTRICTION EXPLANATION:
  The edge selected for filleting is a Tangent Edge
  and not a Tangent Intersection Edge.
  Tangent Intersection Edge is an edge generated by
  an operation such as Boolean, trim, etc. These
  edges are calculated based on the intersection of
  two faces and hence the calculation results are not
  much i.e. the number of possible edges for such
  cases are few.
  The Re-routing algorithm takes into account the
  feasibility and stability of every possible edge.
  When any changes are made to such edges the
  automatic re-routing algorithm has less number of
  possibilities to be taken into account and hence the
  algorithm can make the correct choice easily.
  In case of Tangent Edge also, the proposed edges
  for calculation exist but the number of possible
  edges are many. Automatic re-routing algorithm
  cannot make choice of correct edge for re-routing.
  The only correct way is to do manual re-routing of
  the edge.
  .
  BY-PASS
  Manual reroute of the edge solves the problem.
  .
