To calculate the parameters of a spiral when curvature change parameters and spiral length are given:
Deg Curve defines the angle in degrees used to compute the radius of the curve, whose length is 100 units long. Using the degree of curve (DCV) parameter, the radius of the curve can be calculated as follows:
Start Deg Curve and End Deg Curve values are available for circular curve in and circular curve out respectively, in spirals of the CS to SC type.
Deg Chord defines the angle in degrees used to compute the radius of the curve whose chord length is 100 units long. Using the degree of chord (DCH) parameter, the radius of the curve can be calculated as follows:
Start Deg Chord and End Deg Chord values are available for circular curve in and circular curve out respectively, in spirals of the CS to SC type.
