•ReferencePointArray – array of Reference Points for curve creation
Starting with ReferencePoint class, which can be created using simple XYZ location, using Transform or one the 5 subclasses that allow a point to be placed in reference to some other geometry in the model. This allows us to, for example, place a reference point at the center of a edge and have that point update its location if the edge gets longer or shorter.

Reference point array is an array to store reference points class which is then used to create a curve by points.
