get vertices for an edge query?

adamohernadamohern Member, OS Professional Posts: 216 PRO
My feature queries for an edge, and I need to know the locations of its endpoints. How do I do that?

(Apologies for the noob question, but I've been digging for twenty minutes and can't find it.)

    Something like this should work, though there may be a better way.
    const endpoints = qVertexAdjacent(edgeQuery, EntityType.VERTEX);
    for (var vertex in evaluateQuery(context, endpoints))
        const point = evVertexPoint(context, {
            "vertex" : vertex

    The qVertexAdjacent() gets the vertices of the edge and calling evVertexPoint() on each gives you their coordinates.

    Another option if you, for example, know you have an edge with two endpoints is:
    var lines = evEdgeTangentLines(context, { "edge" : edgeQuery, "parameters" : [0, 1] });
