APAR status

• Closed as suggestion for future release.

Error description

• INFRA : Open several Drawing and saving to gl2
  format generates 1KB size
  .
  SCENARIO:
  1. Open Drawing1.CATDrawing
  2. Click on File menu and select Save As option
  3. Select gl2 format and save the file
  .
  OBSERVATION1:
  Go to windows explorer and check saved file
  properties. It is about 16MB. Plot this data and it is
  printed correctly
  .
  4. Close CATDrawing
  5. Open Drawing1 - Drawing5 (all 5 files)
  6. Activate Drawing1.CATDrawing window
  7. Click on File menu and select Save As option
  8. Select gl2 format and save the file
  .
  PROBLEM:
  Go to windows explorer and check saved file
  properties. File size is about 1KB. Impossible to
  plot TIF

  Incident Diagnosis
  When loading several drafting embedding a very
  large image, some of the draftings do not display
  the image and exporting these darfting to GL2 is
  failing.
  .
  This image requires a very large allocation (close
  to 200Mb) to stay in memory. Loading and
  displaying this image require at least two such
  allocation for each image. Such large amount of
  contiguous memory is very rare on 32bit.
  Therefore after few such allocations, the followings
  images fail to get loaded.
  .
  Since CATIA is not able to visualize the image, it
  means no more large allocation is possible.
  Therefore no export to GL2 is possible as this also
  requires memory.
  .
  Development Request Justification
  Only efficient way to handle such issue and to allow
  user to open many large images till total usage of
  any available memory is to split these large images
  into smallest ones.
  Another possible investigation would be to keep
  these images compressed in memory (but that
  would impact performance greatly).
  .
  This is a very important development with many
  impacts on Visualization and Print algorithms.
  Such development cannot be done without
  enchancement request
  .
  Answer and By-Pass
  Load one Drawing at a time or use 64bit machine
  .
