sheet metal selecting vertices issues?

sacred_heart_college_john_o_shea

Hi,

I'm trying to add some holes at selected vertexes on my flat sheet metal build but for some reason I can't pull the coordinates from the vertex's which is causing issues.

Anyone got any ideas on how i get the vertices locations to add to a sketch which is on my flat panel?

Code below keeps telling me the points are strings and when i print them they show as undefined…
FeatureScript 2491;
import(path : "onshape/std/common.fs", version : "2491.0");

annotation {"Feature Type Name": "Bend Indicators"}
export const mySimpleInputFeature = defineFeature(function(context is Context, id is Id, definition is map)
{
precondition
{
// Allow the user to select a face from the flat pattern
annotation { "Name" : "Select Flat Pattern Face", "Filter" : EntityType.FACE && AllowFlattenedGeometry.YES, "MaxNumberOfPicks" : 1 }
definition.selectedFace is Query;

    // Allow the user to select multiple points on the flat pattern for drawing circles
    annotation { "Name" : "Select Points for Circles", "Filter" : EntityType.VERTEX && AllowFlattenedGeometry.YES, "MaxNumberOfPicks" : undefined }
    definition.selectedPoints is Query;
}
{
    // Ensure a face is selected
    if (isQueryEmpty(context, definition.selectedFace)) {
        throw regenError("You must select a face.");
    }

    // Ensure points are selected
    if (isQueryEmpty(context, definition.selectedPoints)) {
        throw regenError("You must select points where the circles will be drawn.");
    }

    // Query debug: Ensure we are selecting flat pattern geometry correctly
    println("Selected flat pattern face: " ~ definition.selectedFace);

    // Get vertices from the flat pattern context (the points you selected)
    var flatPatternVertices = evaluateQuery(context, definition.selectedPoints);
    println("Number of vertices in flat pattern: " ~ size(flatPatternVertices));
    
    // Check if there are vertices
    if (size(flatPatternVertices) == 0) {
        throw regenError("No vertices found in the flat pattern.");
    }

    // Use the selected face as the sketch plane
    var face = definition.selectedFace;

    // Create a sketch directly on the selected face
    var holeSketch = newSketch(context, id + "holeSketch", {
        "sketchPlane": face  // Directly use the selected face as the sketch plane
    });

    // Iterate over the selected points and add 3mm diameter circles at each point
    for (var i = 0; i < size(flatPatternVertices); i += 1)
    {
        // Use the vertex point directly to create a circle
        var vertexPosition = evVertexPoint(context, { "vertex": flatPatternVertices[i] }).position;
        println("Vertex " ~ i ~ " position: " ~ vertexPosition);

        // Add a 3mm diameter circle at each vertex
        skCircle(holeSketch, "circle" ~ i, {
            "center": worldToPlane(face, vertexPosition),  // Project 3D point to 2D plane
            "radius": 1.5 * millimeter  // Radius = 1.5mm for a 3mm diameter circle
        });
    }

    // Solve the sketch
    skSolve(holeSketch);
}

});
