1. Extract the coordinates of the poles (CoordinateExtractor)
2. Add the coordinates of the poles to the polygons (PointOnAreaOverlayer, merge attributes)
3. Add these coordinates to the points (PointOnAreaOverlayer, merge attributes)
4. Turn the points into lines by adding a new starting point (VertexCreator, insert point at index 0)

Hi,

It did not work.

If the attributes with the coordinates (that you created in the CoordinateExtractor) are not available in the VertexCreator, you did not correctly set 'Merge Attributes' in one (or both) of the PointOnAreaOverlayer transformers.

Thank you very much
