Yes, currently you can specify a coordinate, e.g. 0 for first and -1 for last, or get all coordinates, but if you want just the first and last coordinates you either need to use two coordinate extractors or extract all coordinates and identify the first and last from the list produced.
Simple, add a coordinate extractor and return the -1 X \\ Y to end attributes. Right click and add an X \\ Y begin attribute, for the values use @XValue() and @YValue(). These will extract the begin index of a line.
Definitely a thumbs up for this one. For topology checks being able to extract the First and Last in one transformer rather than having to chain 2 together makes sense. Even if there was a table interface where you could list the vertices you wanted maybe defaulting to start and end in the tool. It would also be good if there was checkbox option to “create points from extracted vertices”.
To extract the endpoint geometry, you can use a pair of Snippers in parallel. In the first, set the Snipping Mode to Vertex, and the Start and End Vertex to 0 to get the start point as a point. In the second, set the Snipping Mode to Vertex, and the Start and End Vertex to -1 to get the end point as a point.
