  Incident Diagnosis
  PDG / RIBS ALONG X-Y-Z DIRECTION NOT
  CREATED CORRECTLY if center curve not planar:
  bad shape with undesired rotation
  .
  Development Request Justification
  .
  Rib moving axis is not fully defined by user
  selection when neither a pulling direction
  nor a reference surface is selected.
  Sweeping software computes a vector called
  viewing direction, that will be constant all along the
  sweeping motion.
  For a planar center curve, this vector is normal
  to the center curve plane.
  For a non planar center curve, this vector is
  the best vector found, that is the vector that
  maximizes the minimum angle with the tangent
  to the center curve.
  Here, with this fully 3D center curve,
  it is impossible to find a satisfying vector.
  So when the tangent to the center curve becomes
  close to this viewing direction verctor,
  an undesired rotation of the moving axis
  causes the poor quality of the result.
  .
  A solution will be to break sweep computation in
  several independant computations on planar
  center curve subsets, or to use
  a local viewing direction, with good management
  of transitions from one center curve edge to the
  other.
  This is a matter of study and development
  .
  Answer and By-Pass
  .
  Break center curve in several planar center curves
  and make as many ribs
  (in this case break center curve in 2)
  .
