HC78876: 3D WIRE : THE EXTRAPOLATED WIRE BODY IS INVALID DUE TO SELF INTERSECTIONS

APAR status

• Closed as program error.

Error description

• SCENARIO:
  1. Open the provided part
  2. go to wireframe & surface
  3. Select split icon
  4. Element to cut : extract.1
  5. Cutting element: Trim.1
  ===>This will result in an error Split.1: Extrapolate a wire
  body: Extrapolated wire body is invalid due to self
  intersections: Modify the wire body or the input used to
  generate it.
  .
  How can the Extract.1 or the trim.1 be self intersecting
  when they are created out of a solid (imported from V4) that is
  good enough to be used in boolean operations.
  .
  

Local fix

Problem summary

•  INCIDENT DIAGNOSIS:
  The intersection operation does not work with the extrapolated
  wire body.
  .
  

Problem conclusion

• THIS PROBLEM WILL BE FIXED ON
    CATIA VERSION 5 RELEASE 7 GA level.
  
   TECHNICAL EXPLANATION FOR THE CORRECTION:
  The "No Intersection" message was due a bad operation of
  intersection with lw wire and shell. Corrections have been
  provided in the intersection functionnality.
  Corrections have been provided also in the SPLIT functionnaliy
  with a development provided for the holes management.
  And the V5 tolerance is equal to V4 tolerance/100. So the
  transmission of a V4 model to a V5 model is though sometimes.
