Show HN: Atopile – Design circuit boards with code

Ya OpenSCAD is great for in/cross project re-usable components.

The only issues I've had is how it outputs circular things for cutting - it does a series of polygons (configurable number), rather than an arc/circular - places like send-cut-send won't accept it, claiming it causes issues with their machines.

Old issue, but annoying nonetheless. Less of a problem when outputting STL files (for printing) which only support polylines and not arcs/circles. Funnily enough, 3D printers nowadays support arcs natively in G-code, so some slicers support detecting rounded polylines and converting them back into circles or arcs.

Found a script[0] that does this for DXFs in a github issue[1].

I actually opened that issue - I'm ukd1 on github too. I looked at fixing it at some point, but it tbh didn't seem that easy or like they had time to help, I should probably revisit. The script I couldn't get working right last time I tried, but I should give it a re-look!
