 +#   Additionally helper points U, V and W are defined, as well as T
 +#   Calculation is based on defining helper line XZ, parallel to SF.
 +#   In the middle between points U and W, is point V, which is also
 +#   the middle point between points X and F. The line UW is perpendicular
 +#   to line XZ. Furthermore, the distance of the line:
 +#     UW = 0.5 * w_trench + w
 +#   Therefore the distance of points UV is m = 0.5 * UW
