Problem conclusion

• THIS PROBLEM IS PERMANENT RESTRICTION IN
  CATIA
  Incident Diagnosis :
  Problem updating a drawing from a big assembly
  Memory allocation failure
  Restriction Explanation :
  There are several things which should correct these
  kind of memory allocation faillure (2 gigabytes
  limit):
  Check your operating system (see "CATIA
  Operating System Considerations" on program
  directory):
  - On Windows XP Professional since CXR14 Level it
  is possible to run CATIA on 3 GigaBytes (System
  must be tuned accordingly, with correct amount of
  physical memory + paging space)
  - On HP-UX since CXR14 Level it is possible to run
  CATIA on 3 GigaBytes (same remark, maxdsiz
  kernel parameter should be sized to accommodate
  up to 3 GB of data)
  - On SUN platform, you just have to check the
  Amount of Real memory and paging space to
  enable 3 Gigabytes usage
  - On AIX platform it is possible to increase
  available memory up to (about) 2.25 GigaBytes
  (explainations are available in program directory).
  - For your information, CATIA main applications
  are validated for 64 bit on CXR16 level.
  .
  Choose following options to save memory. With the
  provided settings, the update of the provided
  drawing (1 projection view and 1 section view) ran
  up to 2174 megaBytes on XP.
  - When turning undo stack to 0 and "No automatic
  backup" option ON, update memory peak decrease
  to 2142 megaBytes (this is a R17 enhancement)
  - When turning cache option ON and
  turning "occlusion culling" option ON for both views
  (view + edit properties) update memory peak
  decrease to 1994 megaBytes
  - You can save some more memory when you want
  thread generation : see "Thread: generates
  threads" part in generative drafting documentation
  to get information on this CXR17 enhancement
  which deals with "technological results".
  In a word, it enables you to benefit thread
  generation without loading in session the complete
  CATPart document.
  Thus we save additionnal memory.
  - Turn OFF the drafting option "Exact preview for
  view generation"
  .
