n
Low point label box: Type the text for marking the lowest elevation point of
a vertical curve.
n
Point of vertical intersection (PVI) box: Type the text for marking the
(vertical) intersection of two tangents.
n
Algebraic difference (A.D.) box: The label indicates the algebraic difference as
a percentage. (Grade of the tangent out of the vertical curve, subtracted from
the grade of the tangent into the vertical curve.)
n
Curve coefficient (K) box: The label indicates the curve coefficient; also
known as the K value of a curve. The K value or curve coefficient is the
horizontal distance needed to effect a 1% change in grade on the vertical
curve.
Changing the Values Settings for Profiles
The profile values settings control stationing increments for labels and grid
lines, minimum K values for sag and crest vertical curves, sight distance values
for vertical curves based on passing height and stopping height, and label
precision values.
To change the values settings for profiles
1 From the Profiles menu, choose Profile Settings
ä
Values to display the Profile
Value Settings dialog box.
2 Under Stationing Increments, do the following:
n
In the Tangent labels box, type the distance between tangent elevation
labels.
n
In the Vertical grid lines box, type the vertical grid line increment. This
increment is the horizontal distance between vertical grid lines.
n
In the Vertical curve labels box, type the distance between vertical curve
elevation labels.
