In the left viewport, notice that the triangulation of the arcs along the
ramp has improved.
To continue this tutorial, go to

Exercise 2: Adjusting Grading Triangulation with a
Feature Line
In this exercise, you will use a feature line to break a poorly triangulated
grading surface.
The triangles in the area on the right side of the ramp are steeper than desired.
These triangles can be corrected by creating a feature line to break the surface
in this area.
For more information, see the AutoCAD Civil 3D Help topic Editing Feature
Lines.
This exercise continues from
Exercise 1: Smoothing Feature Line Arcs
(page
412).
Use a feature line to adjust surface triangulation
NOTE
This exercise uses
Grading-7.dwg
with the modifications you made in the
previous exercise.
