Empty object

udif

What is the canonical way to create an empty OpenJSCAD object?
I have some code where I need to union() several objects, but each of them is optional.
I would like to write something like:

o = empty_object()
if (cond1) {
  o = union(o, ...)
}
if (cond2) {
  o = union(o, ...)
}
if (cond3) {
  o = union(o, ...)
}

I can probably do something like:

o = intersect(cube(), translate([0, 0, 100], cube()))

But I would rather have something more descriptive.

@udif great question!

There are three main objects; geom3, geom2, and path2. You can create empty versions of these…

const a = geom3.create()
const b = geom2.create()
const c = path2.create()
