  • Select the Reference String – this could be a Road Centreline Super Alignment and the Chainage will be calculated from this string, and the calculation between strings 1 and 2 will be perpendicular from the reference string, even if the strings are not.
  • Select String 1 – Pick the string to start the Xfall measure from, ie a Top of Bank String.
  • Select String 2 – Pick the string to finish the Xfall measure from, ie a Bottom of Bank String.

  • ch = Chainage from the Reference String.
  • xf = Xfall calculated between the 2 strings.
  • w = Width calculated between the 2 strings.
  • dz = The Delta Z value calculated between the 2 strings.
