Note: When making a new horizontal segment tangent to the

previous segment, the new segment will appear in the Edit

Alignment screen tagged with a

(P)

. This means that if the previous

horizontal segment is edited or deleted, where the orientation

changes, all subsequent horizontal segments that have the

(P)

tag

will also be adjusted so they will remain tangent to the previous

segments.

This does not hold true for vertical alignment segments. Vertical

segments will always begin with the specified starting grade unless

they are manually modified.

/ : is used to enter a known azimuth or bearing

of the line.

: adds the line to the current horizontal alignment.

Edit Segment – Arc (Horizontal Curve) Card

The Arc card is used to add a horizontal curve to the alignment.

The curve can be defined by two of the following:

• : The distance from the radius

point to the curve

• : The internal angle from center to

tangent points.

• : The internal angle

equivalent to a 100-ft arc length.

•

The internal angle

equivalent to a 100-ft chord length.

• : The arc length.

• : The chord length.

• : The distance from the PC or PT to the PI.
