Show HN: Flyde – an open-source visual programming language
As a visual person (traditionally trained as a graphic artist), I've wanted this sort of thing for a long while, and I've been trying to use it for 3D.
Surprisingly, there are multiple specialized tools for this:
- https://www.blockscad3d.com --- an adaptation of Google's Blockly to OpenSCAD
- https://github.com/derkork/openscad-graph-editor --- wires and nodes, it has the advantage of exposing _all_ of OpenSCAD's commands (the above has a subset)
- https://github.com/Tanneguydv/Pythonocc-nodes-for-Ryven --- a module for using PythonOCC in Ryven --- when I finally succeeded, I found the language inscrutable, even when provided w/ quite nice examples (definitely a failing on my part, not that of the tool)
- https://github.com/graphscad/graphscad --- it took a long while for the source code for this to be made available, and for a while it had compatibility problems (why was "cube" redefined?) --- probably defunct for political reasons, it had some interesting ideas, in particular the ability to have custom icons for modules
- https://www.nodebox.net --- if memory serves I got hung up by not easily being able to do 3D, and when doing 2D having precision problems (or maybe that was Processing.org)
and I've been using these tools to make various things:
https://willadams.gitbook.io/design-into-3d/3d-project
(and maybe eventually I'll finish something)
The problem I've been running into is there doesn't seem to be an answer to the question:
"What does an algorithm look like?"
I recently had occasion to mention Herman Hesse's _The Glass Bead Game_ (also published as _Magister Ludi_) and I'll bring it up again --- what is a meaningful graphical representation of a program?
The Drakon folks argued that there should be one true path but that's not really communicative and I would note that if this was a simple thing it wouldn't be decades since I last saw a physical Flowcharting Template:
https://americanhistory.si.edu/collections/object-groups/flo...
(and it's pretty rare to even see a well-done electronic drawing of a flowchart since Visio made its splash and vanished into the bowels of Microsoft)
The main problem seems to be one of expressiveness not scaling up well, hence:
https://blueprintsfromhell.tumblr.com/
https://scriptsofanotherdimension.tumblr.com/
Presumably, one doesn't want to define modules/variables unnecessarily --- but the question becomes where is that boundary?
If you define too many, then you're back to the "wall of text" which one was trying to avoid (but wrapped up in nice boxes with some lines or shapes), and if one doesn't use them (well, look at the pretty/awful images in the links above).
Ideally, a well-coded visual program would have a pleasing aesthetic appearance which is expressive and communicates flow and function, and I've tried for that at:
https://willadams.gitbook.io/design-into-3d/programming
(though I wish that there was an easy way to export an SVG version of a program)
I believe that what is needed here is some graphical equivalent to Literate Programming: http://literateprogramming.com
Is there a nice GUI toolkit integration which would allow making a graphical application with this? I have an idea I want to try it which might be a good fit.
- Parametric for the win... until it isn't.

Ask HN: Visualizing software designs, especially of large systems (if at all)?
"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
to work up designs which I'm then putting into other tools.
Looking at GraphSCAD:
http://graphscad.blogspot.com
and there's also Ryven and pythonocc which I managed to get installed:
https://ryven.org
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.
- Finally managed to get PythonOCC Nodes for Ryven installed (on Windows --- will have to try again for Ubuntu) --- here are my notes
- What is the one feature that would get you to try a new CAD software?
cadquery
- GitHub - CadQuery/cadquery: A python parametric CAD scripting framework based on OCCT
- Better OpenSCAD?

Best module for generate sketch
I was thinking about cadQuery or DrawSVG. But maybe you have a better idea ? I'm beginner in python (started on november ...)

Synth Printer: 3D printed synth panels with simple Python code. Give me early feedback?
Last few months, I've made over 20 3D printed panels using the CadQuery Python library. Its syntax is pretty complex, so every time I wanted to make a panel, I'd just copy-paste bits and pieces from my previous panels. In the process, I learned what work and what doesn't, and I thought it was time to polish up this system to share it with others.

This subreddit now says that the Steam Deck is just a PC right when you join it. Now all of you who say that it isn't a PC can stop arguing about it
Spicy! I'm also a solidworks user but I've been playing around with cadquery recently, that installed and performs pretty nicely on Linux for me. Haven't really pushed it though.

Pipeline to automate the process from creating 3d objects to start a print job
I am currently developing a pipeline for creating STL files, slice them and create a print job based on it. My setup at the moment is an Ultimaker S5, which offers a simple REST-API, for example starting a job with a G-Code or UFP file. I am using the cadQuery library for creating parametrized 3d shapes and export them as a STL file. I want to use the CuraEngine CLI interface (Backend for Cura) for slicing or their library libArcus (python bindings) but there is literally no documentation or any kind of examples, except the source code. There is also the prucaSlicer, which also offers a CLI interface for creating G-Code, but no support for the Ultimaker S5.

What is the end purpose of your OpenBSD system?
CadQuery would be a closer alternative to OpenSCAD. Not sure if it’s available on OpenBSD.
