"What does an algorithm look like?" I'm an intensely visual person, but have never found a visual programming system which scales well --- the problem is, past a certain level of complexity one has to use modules, which then devolves the visual representation down to just a bunch named blocks. That said, I'm using BlockSCAD: https://www.blockscad3d.com/community/projects/1421975 https://www.blockscad3d.com/community/projects/1421975 to work up designs which I'm then putting into other tools. Looking at GraphSCAD: http://graphscad.blogspot.com http://graphscad.blogspot.com and there's also Ryven and pythonocc which I managed to get installed: https://ryven.org https://ryven.org https://github.com/Tanneguydv/Pythonocc-nodes-for-Ryven https://github.com/Tanneguydv/Pythonocc-nodes-for-Ryven but I'd really like to see a tool for this sort of thing which made G-code.
