The third option uses a light weight geometry provided for generating large amounts of geometry without the overhead of the full nodes. These DSeries geometric elements are created temporarily and use very little memory in the system and therefore are a fast and robust way to script geometry when only the minimal geometric information is needed. There are a number of nodes that have techniques that can directly use DSeries geometry to create nodes such as the ByPointsOnCurveAsDPoint3ds technique for the BSplineCurve.
