How to go from an enum in a UI to a value or specification?

Ok so I am fairly new and not great at featurescript, but I am making a feature that will generate metal tubing. So I have it to where the user selects from a few dropdown menus but I do not know how to make that selection determine the parameters for the part. Here is the feature as it stands-

FeatureScript 1803;

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

export enum daave 

    {

        annotation {"Name" : "Thick Wall"}

        thiq,

        annotation {"Name" : "Thin Wall"}

        thin,

    }

export enum diive

    {

        annotation {"Name" : "1x1"}

        ONE,

        annotation {"Name" : "2x1"}

        TWO,

        annotation {"Name" : "2x2"}

        THREE,

    }

annotation { "Feature Type Name" : "Tube Generator" }

export const myFeature = defineFeature(function(context is Context, id is Id, definition is map)

    precondition

    {

     annotation {"Name" : "Dimensions"}

     definition.Dimensions is diive;

     

     annotation {"Name" : "Thickness"}

     definition.Thickness is daave;

     annotation { "Name" : "Length" }

     isLength(definition.myLength, LENGTH_BOUNDS);

    }

    {

        

        // Define the function's action

    });

This question is a little open ended but the general idea is that in the code block with (//define the function's actions) you'll probably end up with some control flow such as an if statement where you check the users input in a way similar to this (definition.Thickness == daave.thin),  this would evaluate to true if the user selected that option in their feature dialog and false if not. This seems to be the general way to change the behavior of your FS based on which selection was made in the dropdown menu.

Hi @jack_white396, here is one way you can do this. Also, check out this feature script course here.

Fun fact: I did this on my phone.
