HE03581: QSR: AUTOMATIC SURFACE: SURFACE IS NOT CREATED BY AUTOMATIC SURF ACE COMMAND AND UPDATE ERROR OCCURS.

APAR status

• Closed as Permanent restriction.

Error description

• SCENARIO:
  (Problem is data specific)
  The stl data was saved in DMU Kinematics with applying
  wrapping and grain size as 0.2mm, zero offset value, when
  opened in Digitized Shape Editor and cleaned with Mesh
  cleaner.
  When try to create Automatic Surface in Quick Surface
  Reconstruction workbench update error showing message
  ???Automatic surface computation failed: No Result??? is thrown.
  
  .
  EXPECTED RESULT:
  Surface should be created by Automatic Surface command
  without giving update error message.
  

Local fix

• empty

Problem conclusion

• THIS PROBLEM IS PERMANENT RESTRICTION IN CATIA
  Additional Closure Information:
  .
  INCIDENT DIAGNOSIS:
  Unable to create Automatic surface and Update error appear.
  .
  RESTRICTION EXPLANATION:
  Automatic Surfaces command has been developed mainly for free
  form shapes and not mechanical shapes presenting sharp edges.
  With BR data, the mesh resulting from the swept volume
  command presents sharp edges.
  However Automatic Surface does not work well on mechanical
  part with sharp edges and therefore error message appear
  while creating Automatic surface.
  .
  By-Pass:
  1. Clean the mesh to delete the duplicated triangles
  2. Split it in two parts
  3. Use the automatic surface with the regular stream lines
  option
