Problem conclusion

• THIS PROBLEM IS PERMANENT RESTRICTION IN
  CATIA
  Incident Diagnosis:
  Unfold operation fails with update error informing
  build of unfolding failed.
  .
  Restriction Explanation:
  The Stiffened rib (both the sides i.e. top & bottom)
  is intersecting the transformation axis (the
  transformation axis is the axis of the cylinder faces
  of the bend).When the rib intersects the
  transformation axis then unfold is not possible. This
  is a restriction.
  When rib length is more than 15 mm & upto the
  length for which the rib's top & bottom faces
  doesn?t intersect the transformation axis, then the
  faces become too complex to be transformed. In
  this case also unfold is not possible. This is also a
  restriction.
