12.5.2.10 MultiCurve Class

A MultiCurve is a geometry collection composed of Curve elements. MultiCurve is a noninstantiable class.

MultiCurve Properties

  • A MultiCurve is a one-dimensional geometry.

  • A MultiCurve is simple if and only if all of its elements are simple; the only intersections between any two elements occur at points that are on the boundaries of both elements.

  • A MultiCurve boundary is obtained by applying the mod 2 union rule (also known as the odd-even rule): A point is in the boundary of a MultiCurve if it is in the boundaries of an odd number of Curve elements.

  • A MultiCurve is closed if all of its elements are closed.

  • The boundary of a closed MultiCurve is always empty.
