Swapping the Skin

Skin Swapping swaps geometry from an engineering surface to a manufacturing surface, using a normal projection.

  1. In Stacking (Manufacturing), select a ply, a sequence, a group of plies, cut-pieces, an edge of part or a stacking where you want to insert the swapping.

    The engineering surface to be swapped is already selected under Swap.
  2. Select the manufacturing surface with which you want to swap the engineering surface.
  3. Optional: Click Invert to reverse the draping direction and be consistent with the direction defined in the engineering plies.
  4. Select the Swapping mode.
  5. Select a Continuity type (correction mode for the smoothing).
    • No smoothing: This is the default mode.
    • Threshold: The tangency and curvature thresholds options are taken into account.
    • Point: No point discontinuity should remain.
    • Tangent: No tangent discontinuity should remain.
    • Curvature: No curvature discontinuity should remain.
  6. Set the Tangency threshold.under which the curve is smoothed.
  7. Select the Curvature threshold check box and specify the discontinuity value above which the curve is smoothed.
  8. Define the Maximum deviation allowed between the initial curve and the smoothed curve.
  9. Optional: If you have selected a stacking, a plies group or a sequence, select the Invert stacking order check box to invert the order of plies during the swapping.
