HD88954: ELECTRICAL (EWR) / WIRE ROUTING FAILS WITH BUNDLE SEGMENTS FROM EXTERNAL CURVE

APAR status

• Closed as Permanent restriction.

Error description

• Scenario:
  .
  1. Unzip the contents into a suitable directory
  2. Start CATIA, and adjust Electrical Repository in
     TOOLS/OPTIONS/Equipment & systems/Electrical Process
     Interfacing tab, to point to the directory where the unzipped
     files are contained (defined as suitable directory at step 1)
  3. Switch to the Electrical Wire Routing tab, and verify that
     set Bend radius according to the wires is set to Never
  4. Then press OK to close TOOLS/OPTIONS
  5. In CATIA open the ASSY.CATProduct from the directory created
     at step1
  6. Switch to the Electrical Wire Routing workbench if not
     already active
  7. Select the New Bundle command, and then select the bundle
     in the geometry area, and finish the command by pressing OK
  8. Press the Select External Systems command
  9. Select the available system (1), press the top arrow (2),
     and then press OK (3)
  10. Press the Automatic Wire Routing command
  11. In the Wire and Wire group routing dialogue, press the top
     arrow to select the wires
  12. Then press the Route button
  
  ERROR: Automatic Routing indicates that wires cannot be
  routed. The report indicates that routes cannot be found for
  any wires.
  
  EXPECTED BEHAVIOUR: The Automatic Wire Routing
  export should indicate that all wires are successfully routed
  Update command should be done correctly
  
  
  NOTE1:
  Network assistant indicates that all segments are connected.
  Also a search for Electrical.'Bundle Segment'.'fully
  connected'=FALSE indicates that all segments are indeed
  connected
  NOTE2:
  If no Bundle Segments are created based on the external curves
  ( Entryline1-3 ) of the manifold, and the adjacent segments
  are directly connected to the manifold - the routing is
  successful. This potential workaround is however unacceptable
  as it will lead to incorrect length.

Problem conclusion

• THIS PROBLEM IS PERMANENT RESTRICTION IN CATIA
  Additional Closure Information:
  The harness is made of Branches, Connectors and Mounting
  Equipments. The Mounting Equipment contains curves that are
  used as external curves for some Branches and three Bundle
  Connection Points. This is not the kind of use the Mounted
  Equipment is designed for. In fact, all the Bundle Connection
  Points of a Mounting Equipment are considered as connected.
  This improper use of Mounting Equipment and the automatic
  data cleaner of Wire Routing command leads to a model where
  the Wires fail to be routed.
  .
  Bypass:
  1. Remove the Bundle Connection Points (Electrical
  publications) from the Mounting Equipment reference or Do not
  use the Check Network option in the Wire Routing.
  2. Deactivate the Mounting Support and perform the wire
  routing.
