Vertical Alignment

We have now added all available horizontal segment types. Next, we

will define the vertical alignment.

independently of each other, the first vertical segment that is defined

will start at the same POB defined above in Step 3.

then tap the Insert button.

14. Tap the V. Grade tab to insert a grade.

Enter a Length of 150 and a Grade of 4%.

15. Tap to add the segment to the vertical

alignment.



16. With End selected, tap the Insert button

again and then tap the V. Curve tab to
insert a parabolic vertical curve. Enter a
Length

of 250 and tap the Get Previous

Grade button to automatically set the Start

Grade

to the ending grade of the previous

section. Enter an End Grade of -2%.
