A Ruled Surface is the surface the system generates by interpolating linearly between corresponding points of two curve entities. The ruled surface data structure comprises the vector representation of the point, 3 dimensional point data for origin, and curve data for both curves. This data can be initialized and accessed through the functions in this object.
