How to copy user sketch to another plane and extrude (Fixed)

Hey all,

I have a predefined user sketch on a default plane, and I'd like to essentially copy that user sketch to a feature script generated plane and extrude it from there.

Is something like that possible through feature script?

FeatureScript 2180;
import(path : "onshape/std/common.fs", version : "2180.0");

annotation { "Feature Type Name" : "Truss" }
export const truss = defineFeature(function(context is Context, id is Id, definition is map)
    precondition
    {
        annotation { "Name" : "Slot Sketch", "Filter" : EntityType.FACE, }
        definition.slot is Query;
        
        annotation { "Name" : "Slot Wall Sketch", "Filter" : EntityType.FACE, }
        definition.slotWall is Query;
        
        annotation { "Name" : "Body Radius" }
        isLength(definition.bodyRadius, LENGTH_BOUNDS);
    }
    {
        opSphere(context, id + "sphere1", {
                "center" : vector(0, 0, 0) * millimeter,
                "radius" : definition.bodyRadius
        });
        
        var plane = createPlaneOnSphere(context, id + "pointPlane1", vector(0, 0, 0), definition.bodyRadius, vector(1, 0.5) * radian);

        opExtrude(context, id + "slot", {
                "entities" : definition.slotWall,
                // Here I'd like to essentially copy the sketch the calculated plane above and extrude from there instead.                
                "direction" : evOwnerSketchPlane(context, {"entity" : definition.slotWall}).normal,
                "endBound" : BoundingType.BLIND,
                "endDepth" : definition.bodyRadius * 2
        });
    });

export function createPlaneOnSphere(context is Context, id is Id, sphereCenter is Vector, sphereRadius is ValueWithUnits, uv is Vector)
{
    // Convert U & V (spherical coordinates) to Cartesian coordinates
    println(uv[1]);
    var x = sphereCenter[0] + sphereRadius.value * sin(uv[1]) * cos(uv[0]);
    var y = sphereCenter[1] + sphereRadius.value * sin(uv[1]) * sin(uv[0]);
    var z = sphereCenter[2] + sphereRadius.value * cos(uv[1]);

    var pointOnSphere = vector(x, y, z);

    // The normal vector is simply the vector from the center to the point on the sphere
    var normalVector = normalize(pointOnSphere - sphereCenter);

    println(pointOnSphere);
    // Create the plane
    var plane = opPlane(context, id + "plane1", {
            "plane" : plane(pointOnSphere, normalVector)
    });

    return plane;
}}

Thanks,

    No need to move the sketch - create the extrude, transform, boolean

    Yep, got it, thanks. Starting to understand feature script more:
