Description
Calculates the coordinates of the centre of the arc.
of station and offset values in relation to an arc.
Calculates the base point, the station and offset of a
point in relation to an arc.
Calculates the coordinates of new points on an arc
either equally spaced, in a defined interval or in a
defined angle.
The method by which the arc will be defined.
Uses three known points to define the arc.
Defines the arc using two known points and a radius
of the arc.
Defines the arc using two tangents and a radius of the
arc.
Defines the arc using two tangents and the length of
the arc.
