• If selecting Vertical, the cross section of the subgrade stops at
the same horizontal offset as the cross section of the reference
surface.
• If selecting Continue, the last element of both surfaces
selected in the “Maximum extension” entry box is continued.
Select this option if there are more intersection points
expected beyond the end of the cross section.
5. If selecting “Continue” for either the left/right side slope
extension, enter the Maximum extension. This is the distance
(limit) of how far the extension goes beyond the end of the cross
section of the reference surface.
Maximum extension only active if at least one side has
“Continue” selected in the
Extend slope
entry box.

to save the new surface file and end the process.
On the section view, the new road has the same centerline as the
reference surface. The new cross section consists of grade elements
with the same user defined grade value (Figure 3-36 on page 3-40) as
the subgrade. If the cross section of the new subgrade intersects those
of the reference grade, the subgrade shows a new feature line. Dotted
lines in the section window indicates surface information outside of
the last feature line.
