direction of increasing chainage.
For transition from tangent to curve.
For transition from curve to tangent.
Radius of the clothoid. Available for
Method:Radius & length, Method:Radius
& end chainage and Method:Radius &
parameter.

by the system depending on the spiral direc-
tion defined in Spiral direction. Available
for Method:Radius & length and
Method:Radius & end chainage when Use
partial spiral is checked.
The end chainage of the clothoid can be
typed in. Available for Method:Radius &
end chainage and Method:Parameter &
end chainage.
To create a partial clothoid. Available for
