[request] Simple (alternative) public api or static "make" function on objects

Hi,

I think it would be nice to have a simpler public API for scripting / hacking in the spirit of openscad, basically throwing all functions together in a single object, an example of what I mean would looks like this:

import { make } from 'makerjs'

const ball = make.ellipse(18, 18)
const hanger = make.move(make.ellipse(4, 4), [0, 18 + 2])
const ballInside = make.offset(ball, -2)
const hangerInside = make.offset(hanger, -2)
const ballAndHanger = make.union(ball, hanger)
const christmasBall = make.move({
    models: { ballAndHanger, ballInside, hangerInside }
}, [20, 20])

I have got the above somewhat working using my hack below:

interface Make {
    union: typeof maker.model.combineUnion,
    difference: typeof maker.model.combineSubtraction,
    intersection: typeof maker.model.combineIntersection,
}

const make: Make = {
    ...(Object.keys(maker.models).reduce((memo: any, modelName: string) => {
        const lcFirstModelName = modelName.charAt(0).toLowerCase() + modelName.slice(1);
        memo[lcFirstModelName] = (...args: any[]) => new maker.models[modelName](...args)
        return memo
    }, {})),
    ...(Object.keys(maker.model).reduce((memo: any, modelName: string) => {
        memo[modelName] = (...args: any[]) => new maker.model[modelName](...args)
        return memo
    }, {})),
    union: maker.model.combineUnion,
    difference: maker.model.combineSubtraction,
    intersection: maker.model.combineIntersection,
    offset: (modelToOutline: maker.IModel, offset: number, joints: number = 0) => {
        return maker.model.outline(modelToOutline, Math.abs(offset), joints, offset < 0)
    },
    // ... etc

However, the types of the model constructors are not working (as expected) so I would like to turn the above into something like:

const make = {
    belt: maker.models.Belt.make,
    bezierCurve: maker.models.BezierCurve.make,
    // ...etc
}

Most of the models constructors have overloads, which means I would have to re-implement them & keep them up to date (unless there is another way to do it that I am not aware of?)
So I am wondering if it's possible to get this into the core (not necessarily the simple api, but at least the static "make" functions that construct a new instance of those model classes)

Hope this makes sense,

Start by reviewing the public maker.models and maker.model entry points, including the model constructors and combine/outline functions shown in the request. Determine how a core static make API or combined make object could preserve constructor overloads; the work is done when the proposed public API and its TypeScript types consistently construct and manipulate the referenced models.
