Creating an extrusion using dimensions of face parallel to sketch plane.

edited August 5 in FeatureScript
Hello. I am trying to learn FS, and as a step in a larger project, I am trying to get my feature to create an extrusion with the same sketch dimensions as a face parallel to the sketch surface but I am at a loss as to how to best go about this. Do you have any suggestions?

So far I have managed to create a sketch plane where I want the extrusion to be placed, but I am unsure as to which function, query/evaluate, to use in order to get the dimensions of the parallel face and also how I would go about this in general. The main automation in this feature should lie in the identification of the sketch dimensions, the height of the subsequent extrusion is irrelevant at this time.

FeatureScript 1803;
import(path : "onshape/std/geometry.fs", version : "1803.0");

annotation { "Feature Type Name" : "Podium Box" }
export const myBox = defineFeature(function(context is Context, id is Id, definition is map)
    precondition
    {
        annotation { "Name" : "Top Face", "Filter" : EntityType.FACE, "MaxNumberOfPicks" : 1 }
        definition.Topface is Query;

        annotation { "Name" : "Sketch Face", "Filter" : EntityType.FACE, "MaxNumberOfPicks" : 1 }
        definition.SFace is Query;

    }
    {
        //Figure some stuff out      
        var Faceedges = qEdgeVertex(definition.Topface, true);
               
        //Create a drawing plane
        var sketchPlane = evPlane(context, {
                "face" : definition.SFace
        });
        
        debug(context, Faceedges);
        
        debug(context, sketchPlane);
        
        //Create a Sketch
        var faceSketch = newSketchOnPlane(context, id + "sketchFaceplane", {
                "sketchPlane" : sketchPlane
            });
        
        //Draw Stuff        
        skRectangle(faceSketch, "rectangle1", {
                  "firstCorner" : qBodyType(definition.Topface, EntityType.EDGE)* millimeter,
                  "secondCorner" : vector(50, 50) * millimeter
        });
        
        //Solve Sketch
         skSolve(faceSketch);
               

        //  opExtractWires(context, id + "opExtractWires1", {
        //     "edges" : FaceEdges
        //});

        //   debug(context, FaceEdges, DebugColor.BLUE);
        // Define the function's action
    });

I have been stuck for 3 days now, any help would be greatly appreciated.
Best regards

Edward

    Based on your code comments it looks like you've watched the videos from @adamohern. Great resource! This should be doable, and it's all about querying the right thing and evaluating its length. Will you annotate your screenshot to show which dimensions you want to get at with FS to reference?

    Why opExtractWires? opExtrude is what you need.

    I hope the annotations make it more clear as to what I am trying to query, and yes, what and how to query it have been my biggest challenge, as well as how to call it in a function.

    Geometry is generally easier to work with than sketches in Featurescript (perhaps even in Onshape in general ;) ). Here's one solution - link

    I'll give this a go, anything that can simplify the process is a big help haha! :)
