Top 6 Python Opencascade Projects

There aren't many great production-ready open-source frameworks for code-editor components in Swift. I assessed quite a few but found that the feature completeness was far from what I needed. I tried to fork [CodeEditSourceEditor](https://github.com/CadQuery/cadquery) and add the extra features I wanted, but I think it would have taken me 6-12 months to get it to an acceptable state, meanwhile not spending any time focusing on the rest of the product experience.
I decided to play around with Typescript and Electron over a weekend and ended up getting a really solid prototype so I made the heart wrenching decision to move over.
I'm messing around with writing my own text editor component in Swift now, but it's quite a big endeavour to get the standard expected for a production ready product.
I'm assuming a pure-swift CAD UI would be equally difficult. Would be really cool to see that tho.

Project mention: Ask HN: How does modern FreeCAD compare with Solidworks? | news.ycombinator.com | 2024-05-21
I have used build123d to make a few parts recently, and it's a joy to use once you get the hang of it: https://github.com/gumyr/build123d https://github.com/gumyr/bd_warehouse

Project mention: Dune 3D – an open source parametric 3D CAD app bassed on OCCT | news.ycombinator.com | 2023-10-23
> I would love to see a successor to OpenSCAD
There is quite a few "code" CAD's around https://github.com/Irev-Dev/curated-code-cad. Cadquery has contraints but isn't really a DSL.

Project mention: Show HN: Flyde – an open-source visual programming language | news.ycombinator.com | 2024-03-07
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.
