Note: When creating a new horizontal segment and
using the Make this segment tangent to previous option,
the new segment will appear in the Edit Alignment
screen tagged with a (P) (see picture). This means that if
the previous horizontal segment is edited or deleted,
thus changing the orientation, all subsequent horizontal
segments that have the (P) tag will also be adjusted so
they will remain tangent to the previous segments.
Vertical Alignment
We have now added all available horizontal segment
types. Next, we will define the vertical alignment.
The horizontal and vertical alignments are defined
independently of each other, but the first vertical segment that is
defined will always start at the same POB defined for the horizontal
alignment (Step 3).
13. Tap the VAL (Vertical Alignment) tab and 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.
