Absolute beginner understanding of FeatureScript.

I definitely agree with the things Matt lists above definitely including some JS tutorials. I also learned a lot from these tutorials from cadjunkie.com (first ones free, and later one paid, but worth it), and I've been told people got some something from this video I made about using Featurescript to create variables (before Variable Studios were a thing)

@M_Arc when you get stuck, reach back out on the forums and we will help you out. Evan and Konstantin helped me out back when I first started. There are lots of willing FeatureScript devs around.

@M_Arc yes, this is possible. I believe the feature set you are looking for will be Frames. The Cutlist feature can calculate all of the frame data such as length, frame profile, etc... You can copy the cutlist or frames feature then modify it to add part numbers to your frames.

Here is an example of how to copy and modify the Frame feature so that it generates a part number and part name based on profile and longest edge of the frame:

After copying the Frame features code, I added the following to the doFrame() function. The added code will find the selected frame profile description, then search for the longest edge of each frame. Once it finds the longest edge of a frame, it sets the properties for that frame.

    
    var description = profileData["profileAttribute"]["Description"];

    for (var i = 0; i < size(sweepData.sweepBodies); i += 1)
    {
        const body = sweepData.sweepBodies[i];
        const edges = qOwnedByBody(body, EntityType.EDGE);
        const longestEdge = evaluateQuery(context, qLargest(edges))[0];

        const length = evLength(context, {
                    "entities" : longestEdge
                });

        setProperty(context, {
                    "entities" : body,
                    "propertyType" : PropertyType.PART_NUMBER,
                    "value" : description ~ "_" ~ toString(roundToPrecision(length.value, 2))
                });
                
        setProperty(context, {
                "entities" : body,
                "propertyType" : PropertyType.NAME,
                "value" : description ~ "_" ~ toString(roundToPrecision(length.value, 2))
        });
        
        setProperty(context, {
                "entities" : body,
                "propertyType" : PropertyType.APPEARANCE,
                "value" : color(1, 1, 1)
        });
    }

Looks like the DM was quicker and this was just now posted. I'll quote the DM answer for any future users to see:
