This function creates a "median" polyline, that is to say:

  • for each input vertex, other polylines are cut into segments which have the same length ratio

  • then the gravity center is computed for each set of vertices

  • finally, gravity centers are joined so as to create the median polyline

Requirements

Select several polylines and launch the command.

Make sure that the selected polylines have the same direction.
