ILcdCurve
A set of predefined constants are defined in this interface,

Custom implementations can define their own constants, and use them to interpret the interpolation of the curve.

ILcdCurve
This information can be used to perform containment calculations, if this curve is closed or if this curve is part of a composite closed curve. By determining the number of intersections between this curve and a line segment starting from a given point in a fixed direction, one can determine whether a point is located within the closed curve by using the even-odd rule.
