HD72206: SPLITTING OF SHELL OR STIFFENERS

APAR status

• Closed as documentation error.

Error description

• Splitting of Shell or Stiffeners
  SCENARIO:
  1. Shell plate is created in SDD.
  2. Split (break) shell plate with a plane, say Long
  plane (LONG.-10)
  .
  CONCERN:
  One side of plate is split normal to molded surface
  (Not Expected)
  Other side of plate is split as per splitting plane
  (Expected Behavior)
  .
  EXPECTED BEHAVIOR:
  Both the plate should be split as per expected
  behavior (shown in attached PPT slide No. 7 (added
  by BZO))
  .

  Thickness Compensation
  MODIFICATION:
  CurrentThicknessCompensationBehavior
  Thickness compensation for Plates
  The thickness compensation for Plates is the
  operation that consists into trimming the original
  solid representing the Plate to fit in position. In
  other words, it is to obtain the final physical
  representation of the Plate. This doesn't cover the
  Manufacturing Representation of the Plate.
  Only Remove mode is supported for Plate limits.
  The different modes for the nibbling are the
  following:
  Nb. All the drawings are side views.
  Short Point : Ensure contact without
  clash
  Long Point : Ensure full contact (might
  lead to clash)
  Remove : Boolean Operation without
  Extrapolation
  1. Case 1: no intersection between
  Operated and Operating: no operation, the
  operated plate is not changed.
  2. Case 2: clash but no full clash
  3. Case 3: Full clash
  4. Case 4: Contact without clash (Contact
  can be a point/curve/surface)
  MetalToMetal : Extrapolation to ensure
  full clash then Boolean Operation (remove)
  At Neutral Fiber : Extrapolation to
  ensure contact (up to the Neutral Fiber)
  In our scenario, the Remove mode is performed on
  both split Plates P1 and P2.
  The split Plate P2 is in full clash with the
  Splitting plane limit and therefore nibbled by the
  plane as per Case 3.
  The split Plate P1 is not in clash with the
  limit but only in edge contact (case 4 above). As P2
  is not extrapolated before the nibbling, the result is
  as seen below:
  NOTE: I have attached
  CurrentThicknessCompensationBehavior.doc file,
  and information about it will be documented in
  Documentation.
