Curve Solution

Curve Curve Solution.

The Curve Solution screen provides detailed information on a curve

when two parts of the curve are known.

The first known part of the curve is defined by

one of the following:

• Radius : is the distance from the radius

point to the curve.

• Delta : is the deflection angle.

• Degree Arc : is the deflection angle that

results in a 100-ft. arc length.

• Degree Chord : is the deflection angle that

results in a 100-ft. chord length.

The second known part of the curve is defined by one of the following:

• Delta : is the deflection angle.

• Length : is the arc length.

• Chord : is the chord length.

• Tangent : is the distance from the PC or PT to the PI.

• Mid Ordinate : is the distance between the curve and the chord at

the center of the curve’s length.

• External : The minimum distance between the PI and the curve.

Solve : Computes the details for the horizontal curve.

Layout… : Opens the Horizontal Curve Layout screen (Page R-381)

where points can be created so the curve can be staked in the field.

Traverse… : Opens the Traverse on Curve screen (Page R-388).
