If you look at this and you think "wow, I love the idea of CAD-as-code but I wish it was a more sane language" then have a look at CadQuery: https://cadquery.readthedocs.io/en/latest/quickstart.html#qu... (I recommend CQ-editor for an easy install: https://github.com/CadQuery/CQ-editor/releases/) It's a similar idea to OpenSCAD, but embedded in Python and using a better geometry kernel. Want to fillet a box in OpenSCAD? Sure, either take the convex hull of 8 spheres, or the minkowski sum of a box and a sphere. Want to fillet a box in CadQuery? .edges().fillet() Now I'm hearing some protests about Python, but consider this example OpenSCAD code: x = 1; echo(x); x = 2; In most languages you would expect this to print "1". In OpenSCAD, the last assignment wins and it prints "2".

I had some good results using CadQuery [1] with CQ-editor [2] for visualization driven by Claude Code enhanced by a cadquery-llm-skill [3]. I didn't make anything too complicated, just cases for various ESP32 projects I am tinkering with, but that was very easy just describing what I want and iterating and refining until I am satisfied. It was much easier than doing it manually in FreeCAD and more dynamic as the changes were cheap and not tedious to do.

OpenSCAD is my go-to. It's self-contained and AI coding tools know the syntax well enough to help you move fast. Unfortunately I keep hitting a complexity ceiling. If it doesn't like how I'm describing something, it crashes. I have to load an older version of my .scad and try a new approach. This usually happens 70% of the way into a complex project, which is quite discouraging. The Python ecosystem has CadQuery[0] and a few other tools built around the Open Cascade kernel[1] which is quite good in my limited experience. CadQuery is positioned as an OpenSCAD alternative [2], and I really want it to be. Unfortunately the user experience isn't there yet. Making an object with CadQuery is writing a Python program. Which means you need a Python environment and dev setup. CQ-editor [3] is nice, but needs a Python environment first. I think Cad

Query would be much more viable OpenSCAD alternative if it was packaged into a standalone CQ-editor application and published via homebrew, etc. I'm also interest in Zoo [4](fka KittyCAD). They're trying to create a modelling tool that combines model-by-code and model-by-mouse. With some AI layered on top. They have an interesting architecture where they stream geometry to your local device from the cloud. Should be great for performance, but ties you to the cloud.

On a previous laptop I used i3, then after a few years on Windows, I returned to Linux on my current laptop and decided to try Sway, and now I’ve been using it for almost a year and a half, but I set up i3 somewhere along the way too, which I have used when I needed screen sharing on Zoom. I much prefer Sway. It handles output management much better than i3 (because it’s integrated and integrated well rather than being entirely up to you with xrandr—so this probably wouldn’t apply to full desktop environments like GNOME or KDE), supports mixed-DPI environments, properly supports high-DPI (though I’ve also been using patches for fractional scaling since I want 1.5×), avoids all tearing (which was what really surprised me when I first ran i3, I’d forgotten what the tearing was like), and supports my XF86AudioMicMute key (key code 256; it to

ok a little effort to get it to work, involving dumping the xkb keymap and adding in a suitable entry, but I think that it’s literally impossible to support under X, though you may be able to remap it to a different key like F20 in some way at a lower level, but my attempts at that failed). It’s not been without its troubles. Screen sharing is only possible at the screen granularity rather than individual windows, and I think Zoom is still broken because they did things stupidly in the past (using a GNOME screenshot API many times per second instead of the compositor-neutral screen sharing API that did exist when they implemented their thing) and are still unravelling them. I’ve also had a couple of apps require tweaks to unbreak, e.g. https://github.com/CadQuery/CQ-editor/issues/266, if you build it with a version of Qt that supports Wayland (the default, though their first-party distribution doesn’t), you have to explicitly tell it to use xcb instead of wayland or it crashes on startup. But honestly that’s all I can think of. Oh, one more thing, I guess. Cursor sizing is comically broken in Sway. With `seat seat0 xcursor_theme Adwaita 96`, I get cursors at at least five different sizes when hovering over different windows. Some ignore it and use the default size multiplied by the scaling factor. Some use it but ignore the scaling factor. Some use it and multiply by the scaling factor. Some use it and multiply by the scaling factor rounded up to the next integer. Some do different things altogether. I haven’t diagnosed it all yet.

All this talk about anaconda etc is a little overblown. Just grab the release ZIP here and run the launcher. It drops you in the editor/debugger workspace with full functionality. https://github.com/CadQuery/CQ-editor/releases/tag/0.2 It doesn't appear to modify your system in any way. I understand that other modes of using CadQuery require 'conda, but the basic built-in editor experience is self contained. Or am I misunderstanding something?
In CadQuery Comes of Age
I tried this a couple of months ago, I found what it's trying to do very pleasant to use but the tooling around it is very annoying. The up-to-date version 2 isn't on pypi, conda is thoroughly unpleasant to have as an environment. There seems to be a drive to using it inside it's own editor https://github.com/CadQuery/CQ-editor while nice seems like wasted engineering effort in developing an editor when the language needs so much work. I didn't have much success structuring cad into modules as they wouldn't import well. The point IMO of parametric cad in an existing language is to use the ecosystem. Lots of choices in this project make that really hard.

> I'm curious, what makes you so opposed to it I confess to having not kept a very detailed track of the headaches conda has caused me over the years, but here are my recollections: - conda plain and simple failing to install with a cryptic error message after downloading multiple gigabytes of crap only to test a small piece of software. Back then (slow download / disk writes / CPUs), easily an hour wasted. - conda ruining my existing pip install and silently overwriting apt-get managed packages. - conda unilaterally grafting bash code in my .bashrc, a practice I find - to remain polite - distasteful, not to mention the (IIRC) creation of a giant turd of a repo in my home directory. - conda, when used to run tensorflow based packages on my NVidia linux box completely wrecking the existing NVidia drivers installs to the

point of it booting in "safe mode" or giving me a black screen. - post conda install, some binaries didn't want to run anymore because conda-installed libs were newer. To be fair these grievances are old: I've avoided conda like the plague for - easily - the last 5 years, and they might have cleaned up their act. However, I still find the notion of having to install 2 gigs worth of stuff on my machine only to try a simple CAD package for a few hours a rather offending proposition. Call me an old curmudgeon if you have to. To be fair to the cadquery folks: they seem to have realized the issue and they now offer what looks like a somewhat self contained binary dowload of the cq-editor package [2]. Finally, I'll leave you with this, taken from the cadquery homepage itself [1] (note the use of the word "polluting" in there, looks like I'm not the only one feeling this way): For those unfamiliar (or uncomfortable) with Anaconda, it is probably best to install Miniconda to a local directory and to avoid running conda init. After performing a local directory installation, Miniconda can be activated via the [scripts,bin]/activate scripts. This will help avoid polluting and breaking the local Python installation. In Linux, the local directory installation method looks something like this [1] https://github.com/CadQuery/cadquery#alternative-anaconda-in... [2] https://github.com/CadQuery/CQ-editor/releases
