| Abstract: | Based on the arc length formulae of the parallel to the easement curve and its property, this paper gives the parameter equations of the parallel to the easement curve taking the arc length itself as variable. It presents the rigorous method to calculate the intersecting point coordinate of the straight line with the parallel to the easement curve. By case history calculation, it proves that this method is characterized by its simplicity of solution principle and covenience in computer programming. |
