In place of a line bent every ten metres to keep within 0.1 m of every bump, the grades and the vertical curves are fitted to the ground the way the profile fits them. Where the formation is made in the terrain model the line keeps to the radius of the norms and cuts and fills; over the ground left as it is it bends as sharply as it has to. The joints keep the height and the grade of the track joined, no grade is capped and no piece is under 5 m.
