Hi group, You helped me a lot to jump-start the learning curve of FME. And now I'm stuck again. I have polylines (streamsÂ…again) with certain Z value. The streams are not cleaned, meaning I could have bumps in elevation (streams going up the hill and descending). I arranged to have first vertex with the highest elevation and lowest is the last. The troubles are the vertices between. My task is to assign the same elevation, as the previous vertex to the vertex with the error. Ex. Of the stream with error list of possible elevations starting with the first vertex: 45, 45, 44, 42, 40, 40, 42, 41, 40, 39, 36, 35,33 As you can see the elevation 42,41 should be 40,40 I thought of using chopper of two vertices, but then if I change elevation at one end the other is not going to be updated. If I cold iterate somehow through the polyline, take first vertex compare with next if it's less or equal, if not put the same elevation as previous vertex and continue.
