Local fix

Problem summary

•  INCIDENT DIAGNOSIS:
  Problem when trying to drive length parameter of a pattern by
  a formula.
  

Problem conclusion

• THIS PROBLEM WILL BE FIXED ON
    CATIA VERSION 5 RELEASE 8 GA level.
  NOTE THAT THIS PROBLEM WILL ALSO BE FIXED ON V5R7SP02.
  
   TECHNICAL EXPLANATION FOR THE CORRECTION:
  Length parameter of a pattern cannot be driven by the user as it
  is the result of spacing*(instances-1).
  The delivered correction is :
  Do not show anymore length parameters to the user.
  It is no more possible to add a formula to a pattern length
  parameter through formula panel (it was not through pattern
  panel).
  .
  Edition of a pattern will remove it for existing patterns.
  Comments will be added in documentation.
  
   ANSWER AND POSSIBLE BY-PASS:
  Instead of length parameter, use spacing * (instances-1)
