Hi Knut, I think it might be easier to work with the Bufferer and try to copy the elevations back onto the feature. Do these features have constant Z values (eg contours or perhaps buildings)? If so, the ElevationExtractor and 3dForcer transformers would do the job very simply.
Otherwise, I think you'll have to drop the line features into points (Chopper), extract the Z coord from each point in the original feature (CoordinateFetcher), copy the Z value to the matching point on the buffered feature (FeatureMerger) then join the buffered points back into a line (PointConnector). And I'd do the process on one side at a time - ie buffer on the left hand side and do the above. Then buffer on the right hand side and repeat - the reason being I'm not sure how well the order of points will match up with more than 2 features.
