I was wanting to use the projection function conditionally in a module but I
get an error, is there a way to do this? This is the code I have that gets
an error

module draw_circle(param1, param2, param3, flat="no") {
if (flat == "yes") {
projection()
}

draw shape code goes here

}

If I take out the if statement like so it does what I want

module draw_circle(param1, param2, param3, flat="no") {
projection()

draw shape code goes here

}

This works:

module draw_circle(param1, param2, param3, flat=false) {
module draw_shape() {
sphere(param1);
}

    if (flat) {
        projection()
            draw_shape();
    }
    else
        draw_shape();

}

Great, thanks. That will require a little re-orgranization of my code
but it will be worth it to have the ability to do.

Or something like this should work:

module conditional_project(flat) {
    if (flat == "yes") {
        projection() children();
    } else {
        children();
    }
}

module draw_circle(param1, param2, param3, flat="no") {
conditional_project(flat) {
draw shape code goes here
}
}

But I would use a boolean rather than a string for "flat".
