HD77895: THE 3DXML GENERATED FILE SYNTAX IS NOT WELL FORMATTED THUS TO X SD AND ARE NOT SUPPORTED BY 3DXML APPLICATIONS

APAR status

• Closed as program error.

Error description

• Abstract: The 3DXML generated file syntax is not
  well formatted thus to XSD and are not supported
  by 3DXML applications (viewer, authoring).
  Scenario:
  1. Launch CATIA V5R19SP1.
  2. Go to
  Tools>>Options>>General>>Compatability>>3D
  XML & selct Xml Tessellation.
  3. Insert the IGES file in new CATProduct & save
  the CATProduct.
  4. Run CATDMUBuilder in order to process the
  IGES file and generate a 3DXML by following
  command:-
  CATDMUBuilder "c:\temp\BuildList.txt" -
  product "c:\temp" -nocache -savedata -
  outputformat 3dxml
  5. Open 3D XML file with winzip and extract the
  3DRep file that contains geometry.
  6. Open the 3DRep file.
  .
  Result:
  This 3DRep file contains some empty VertexBuffer
  nodes (you can look for <VertexBuffer/> string in
  the file). This is not allowed by 3D XML official XSD.
  .
  Expected Result:
  The 3DRep file should not contain some empty
  VertexBuffer nodes.
  .

Problem conclusion

• THIS PROBLEM WILL BE FIXED ON CATIA VERSION
  5 RELEASE 20 GA LEVEL.
  THIS PROBLEM WILL BE FIXED ON CATIA VERSION
  5 RELEASE 19 SP02 LEVEL.
  Incident Diagnosis
  In really specific situations, VertexBuffer field is
  added when there is no vertex in it, which is not
  allowed by the specifications (XSD).
  Correction Explanation
  If there is no vertex in the vertexbuffer, the
  VertexBuffer field is not added in the XML file (test
  with GetNumberOfVertices() method).
  Answer and By-Pass
  Delete all the strings "" present in the 3DRep file
  contained in the 3Dxml archive.
