HE04497: PART DESIGN : UNABLE TO DO A HOLE AND A POCKET ON A SOLID BODY A S A SHEET FOLDED AND JOINED ON ITSELF

APAR status

• Closed as Permanent restriction.

Error description

• Scenario:
  1. Open CATIA.
  2. Open in Part design the CATPart provided.
  3. Activate ???Sketch??? and select the surface.
  4. Make a circle with the following parameters: diameter =
  30mm, collinear with V axis,
  distance between H and circle center = 50mm.
  5. Exit workbench.
  6. Activate ???Pocket???.
  An error will appear:
  Feature Definition error:
  Topological operators: internal error
  7. Select ???OK??? on error and then ???Cancel???.
  8. Activate ???Hole??? and then select an area inside the circle
  .
  Another feature definition error will appear if the default
  parameters of the hole are:
  Blind, 10 for Diameter and 10 for Depth.
  9. Select ???OK??? on error and then modify Depth value to 25,
  then click in the Diameter field.
  
  same problem with the Another CATPart
  Expected result:
  Possibility for the user to make a (through)hole on the part.
  

Local fix

• empty

Problem conclusion

• THIS PROBLEM IS PERMANENT RESTRICTION IN CATIA
  Additional Closure Information:
  Incident Diagnosis:
  Unable to do a hole and a pocket on a solid body as a sheet
  folded and joined on itself
  Reason:
  ThickSurface operator doesn't search for collisions or
  confusions between topologically
  distant parts of a model, for time consuming reasons. Only
  local clashes and confusions are solved.
  That's why there are two superimposed faces in ThickSurface
  result.
  This result is compliant with ThickSurface operator
  specifications.
  But this configuration is problematic for Hole and Pocket
  operators.
  The situation is not handled.
  To solve the confusion between faces, it is necessary to run
  a boolean operator which involves
  them, because boolean operators simplify geometrical supports
  and their topologies when possible.
  
  By-Pass:
  Perform an operation boolean to simplify the body.
