Hello,

I have some 3D Polyline (Polyline ZM) of which I am interested in the lowest/maximum height in order to be able to make a further query with this information. All polylines have a different height at each of their vertices. Is there an elegant solution in FME for extracting the min/max height of a line and then attaching it as an attribute?

Thank you very much for your support.

You can use a BoundsExtractor to get the minimum z and maximum z value of a line. Delete the names for any of the parameters you don't want
