They involve certain distances to origin and their absolute elevations, with the possibility of linking the vertices by means of parabolic or circular sections (vertical transition curves) which will be defined by any of their components: Kv (parameter of the parabola) or R (radius of the circle), Tangent (length in an orthogonal projection on each of the alignments involved) or Arrow (maximum ordinate at the vertex).
