HD78704: PART:UPDATE CYCLE ERROR AFTER PROJECTION

APAR status

• Closed as Permanent restriction.

Error description

• SCENARIO:
  1. Start CATIA.
  2. Open CATPart
  3. Edit "Sketch.2".
  4. Click "Project 3D Elements" command, and
  select the vertex (Surrounded by red circle).
  5. Exit sketcher workbench.
  .
  OBSERVATION1:
  Update cycle error occurs.
  .
  6. Close the above and reopen the CATPart again
  without saving.
  7. Delete REMOVE operation from the tree.
  8. Perform steps 3-5.
  9. Perform Remove Body.2
  .
  OBSERVATION2:
  Boolean operation is performed without any error.
  .

Problem conclusion

• THIS PROBLEM IS PERMANENT RESTRICTION IN
  CATIA
  INCIDENT DIAGNOSIS:
  Update cycle error is generated after projection
  done on a deactivated Remove operation.
  .
  RESTRICTION EXPLANATION:
  Update cycles must be detected because they are
  often design errors. They have to be detected and
  displayed in the error panel, so that user could
  correct them.
  .
  Remove is a modification operation therefore its
  deactivation is done in Copy mode. When
  deactivated, the result of the feature is identical to
  its main input and thus can be selected and
  highlighted.
  When the projection is created on any of the
  sketches which are input for the remove operation,
  it is selected on the result of Remove and hence
  Remove becomes parent of the edited Sketch.
  Thus Remove becomes parent of the Body which is
  used for the Remove operation i.e. Remove has
  become child of its own modification.
  .
  BY-PASS
  Select the geometry of the Sketch used for
  creating the Pad to create the projection instead of
  the geometry from Pad
  .
