Kudos on this, amazing what you did in about 2000 lines of code!

I am sure I am mising something Basic but say I make this command...

text("Hello world!",45, "arial.ttf")

how would I know its width and Height?
I would like to create a name bade for example so I need to know where to put the surrounding rectangle

I would like to be able to output slicer modifiers from my FreePySCAD scripts, this would make writing generators for custom calibration routines really simple.

For example, my typical extrusion multiplier routine could be something like this:

minimum_flow = 95
maximum_flow = 102
flow_step = 1

scene().redraw(*[
    union(
        name="flow_test_{}".format(flow),
        layer_height=0.2,
        first_layer_extrusion_width='140%',
        bottom_solid_layers=0,
        perimeters=2,
        top_solid_layers=8,
        fill_density=0.25,
        fill_pattern='Rectilinear',
        print_extrusion_multiplier='{}%'.format(flow),
    )(
        cube(20,20,2),
        cut()(
            cube(20,28,0.2),
            linear_extrude(0.2, 0, 0)(text(str(flow), 6)).move(1,1),
        ).move(0,-8,0),
    )
    for flow in range(minimum_flow, maximum_flow+flow_step, step=flow_step)
])

The convex hull operation from OpenSCAD is extremely useful for quickly drawing up simple (and not-so-simple) mounting-plates and whatnot. Examples at https://hackaday.com/2018/02/13/openscad-tieing-it-together-with-hull/.

in https://github.com/supermerill/FreePySCAD/blob/master/freepyscad.py#L1846 you list+str.

can't y, and y=z
move(x=10,y=10)(rotate_extrude()(polygon([[0,0],[ray2,0],[ray,2.2],[0,2.2]])))
