I’m trying to identify the vertex/vertices in a 3D dataset which are at the zmin.
The task is very easy but I’m trying to figure out the fastest/cleanest way to do this. The dataset could be quite big and the geometry could be any type (not point cloud or raster).

Are you looking to identify vertices at the zmin which is already known, or find the vertex with the lowest z value which is not yet known?
The zmin is unknown
My current approach is to use:
Aggregator>BoundsExtractor>GeometryPartExtractor(lines)>Chopper(to points)>Tester(z = zmin)
Is just seems I could skip the last few steps and just extract the lowest point directly from the geometry e.g., An “ExtremeVertexExtractor”
If you don’t want to go down the python route, then I would think that getting the vertices as a list, using a list range extractor to find the min z and then a listsearcher to find that coordinate would be more efficient than chopping to points?

Ah nice the ListSearcher - yeah with a list of coordinates and a known z this works well.
Thanks
