    Hello LogoBot architects!
    jmeosbn
    @jmeosbn
    So, to test the syntax highlighting, would this be a handy utility in OpenSCAD?
    // show cross section
module section()
{
    size=1000;
    difference() {
        children();

        color("white")
        translate([0, -size/2, 0])
            cube(size, center=true);
    }
}
    Hmm, syntax support, is a bit different to github..

    Nice idea and yes... Want to add it to a utile script
    Utils script

    Cool, will do - I'll also use it for the LED clip sandbox. Although, after some discussion we'll probably go another way on that (support a vertical light "strip", from the base or battery holder?)
    (Will summarise more fully on the group topic)

    Add a new file in utils/ or add to moreShapes.scad?

    Add to more shapes if you like and cool

    PR sent: when I understand how to mess with vectors I'll add some arguments. (size is easy to add, but should probably be the second arg?)

    Would be nice to pass the section plane as a parameter
    jmeosbn
    @jmeosbn
    Yes, that's what I meant by vector. Feel free - or show me how. ;)
    I had previously tried this with my header spacers - basically, I want to multiply the arguments to a transform, using a vector. Or something like that!
    transform_var = vector_arg * [size/2, size/2, size/2]
    where vector_arg in the default case, would be something like [0, -1, 0]
    jmeosbn
    @jmeosbn
    I actually have the size/2 negated, which makes more sense - but I mistyped above. So, the arg is more like [0, 1, 0].

    But it doesn't seem like OpenSCAD supports this higher level use of arrays/vectors - and I don't want to loop through them when there's probably a simpler way to do it.

    For my earlier use, I wanted a rotation - so I just went with passing in rotation as degrees but that was a bit unelegant. I guess there should be some source that shows a similar use for built-in modules that take a vector.

    I'll draft something tomorrow... Chillaxing with some TV tonight :)

    Cool, I'm about to be too. Quick question if you do see this: can you 3d print over an arch? Like below:

    @Axford
    Ish... Depends on the span at the top of the arch.. It's effectively an unsupported bridge
    jmeosbn
    @jmeosbn
    Hmm.. What'd be a better shape to use, a sharp angle of <= 45° I s'pose?
    Axford
    @Axford
    Yep... The infamous reprap teardrop

    @jmeosbn
    Not heard of that before - but I'd imagine it crops up a lot..
