Re:Benchmark: CadQuery vs. OpenSCAD for agentic CAD work on Sunday September 13, 2026 @02:51AM (#49680785)
assemblies and tolerances are where AI generation quickly gets hard. but, for simpler things, it can be surprisingly good, especially for people who has no CAD knowledge. it certainly might feel a bit like brute-forcing through the LLM - but this also applies to vibe-coding..

Sure! but, for 3d printing hobbyist who wants to create and print a cube, both are able to provide a printable cube.

do you know the WASM bundle size of Python and CadQuery? OpenSCAD has a lot of cons in terms of concept and CAD approach, but there are things where it is good - it is embeddable and sandboxable and fast. It gets the job done in simple models and that is the reason why it is popular. It reminds me a bit how everyone was bashing PHP because 'it is not a programming language' while wordpress ruled the world.

"Downloading WASM: 40mb of Python and build123d" - this hurts :( This is exactly the good thing about OpenSCAD: its WASM build size is minuscule compared to Python build, and you can edit/customize a model right in the browser. https://modelrift.com/models/desktop-organizer-with-drawer

CAD for 3D printing is finally becoming feasible with Flash 3.7 and 3.8. Exciting times. https://github.com/ModelRift/openscad-skill/

https://modelrift.com/blog/openscad-llm-benchmark/ LLMs are still weak at spatial reasoning, but it gets better. Check out modelrift.com for another alternative

take a look at modelrift.com, it is built around annotating built models by basic pen and arrow tools, works fairly well ('smarter' model is significantly better)
Re:GenCAD on Sunday May 24, 2026 @09:42AM (#48257222)
check this out: https://modelrift.com/blog/openscad-llm-benchmark LLMs are getting pretty good at OpenSCAD, especially if they work in agentic mode and can inspect intermediate results.
these small functional prints are exactly where OpenSCAD and LLM generation shines
I agree, my main concern regarding Google AI products is this endless pain around the UX of login / billing / upgrades / product sunsets... but their LLM models are good and Antigravity 2.0 is not that bad either (unless you lost all you Antigravity 1.0 setup and projects - like many people did)
If you like this, you should definitely check modelrift.com which allows to build awesome cad models thanks to OpenSCAD and smart AI assistant.

Did you try modelrift.com ? Its openscad + ai but way more convenient to preview results in realtime and iterate via annotated screenshots

try modelrift.com ? Llms are bad at spatial understanding but you can steer them using annotated screenshots ("annotation mode" of modelrift) and get something working: https://modelrift.com/models/cable-conceal-box-with-wall-mou...

Also check out modelrift.com which is based on openscad foundation. See the dynamic customizer which allows to edit any model parameter, re-render and get .stl: https://modelrift.com/models/customizable-liquid-funnel - it works _completely_ in your browser by using WASM

let me know how it goes!

Re:Gemini 3 Deep Think on Friday February 13, 2026 @06:15AM (#47001465)
building a benchmark is a great idea, thanks, maybe I will have a couple of days to spend on this soon
Re:Gemini 3 Deep Think on Friday February 13, 2026 @06:12AM (#47001452)
right, I need to fix this one
Re:Gemini 3 Deep Think on Friday February 13, 2026 @06:12AM (#47001451)
Thank you for this feedback, very valuable! I am using Bambu as well - perfect to get things printed without much hassle. Not sure if direct push to printer is possible though, as their ecosystem looks pretty closed. It would be a perfect use case - if we could use ModelRift to design a model on a mobile phone and push to print..
Re:Gemini 3 Deep Think on Thursday February 12, 2026 @02:20PM (#46993674)
it is interesting that the video demo is generating .stl model. I run a lot of tests of LLMs generating OpenSCAD code (as I have recently launched https://modelrift.com text-to-CAD AI editor) and Gemini 3 family LLMs are actually giving the best price-to-performance ratio now. But they are very, VERY far from being able to spit out a complex OpenSCAD model in one shot. So, I had to implement a full fledged "screenshot-vibe-coding" workflow where you draw arrows on 3d model snapshot to explain to LLM what is wrong with the geometry. Without human in the loop, all top tier LLMs hallucinate at debugging 3d geometry in agentic mode - and fail spectacularly.
Re:Parametric CAD in Rust on Wednesday January 28, 2026 @07:37AM (#46794526)
If you like OpenSCAD, you should check https://modelrift.com which is an OpenSCAD browser-based IDE which uses LLM to generate .scad and instantly shows the .stl 3d model result via 3d model viewer. Since AI models are still not good at openscad, the useful feature of modelrift is the "screenshot-powered" iteration where human annotates visual problems and sends it back to AI assistant to fix, all using hotkey shortcuts.
