WebSpiral Curve. Used to place a transitional spiral as a B-spline curve. Sets the spiral's mathematical definition. Clothoid — Used to create a smooth transition between arcs that have different radii so that there is no abrupt change of curvature. Used in highway design. An Euler spiral is a curve whose curvature changes linearly with its curve length (the curvature of a circular curve is equal to the reciprocal of the radius). Euler spirals are also commonly referred to as spiros, clothoids, or Cornu spirals. Euler spirals have applications to diffraction computations. They are also widely used in railway and highway engineering to design transition curves between stra…

It is … WebIt is also known as clothoid. Lemniscate Lemniscate is a type of transition curve which is used when the deflection angle is very large. In lemniscate the radius of curve is more if the length of chord is less. Vertical Curves The curves provided in vertical plane of earth is called as vertical curve. chiltern mills in leeds
