      hi everybody,

      i just came across the problem to draw a middleline of a road automatically.

      has anybody an idea, if there is a ruby, which can calculate the middle point in the geometry step by step and draw a line between these centerpoint?

      the red line shall be the result.

      thanx a lot

          hi, thanx, yes, i already tried,
          but at the moment a get doubled lines in the middle , when the offset = 1/2 of the width.

          so creating a curve from the middle - line by WELD does not work yet.

          still trying.

          regards stan

            Alternatively, you could use Curviloft (loft by spline), with

            • the 2 side contours
            • asking for 2 segments (2s)
            • in geometry parameters, as only for grid
