## Interface ITrimCurveI

- All Superinterfaces:
    ICurveI, ICurveOp, IParameter, ITransformable, IVal
  All Known Implementing Classes:
    ITrimCurve

      public interface ITrimCurveI
      extends ICurveI

  Interface of trim curve of surface. A trim curve is either outer trim curve (outside edge) or inner trim curve (edge of hole).
