#52> To my surprise, Zoo’s API didn’t perform particularly well in comparison to LLMs generating STLs by creating OpenSCAD
This is interesting. As foundational models get better and better, does having proprietary data lose its defensibility more?

#53The future: "and I want a 3mm hole in one side of the plate. No the other side. No, not like that, at the bottom. Now make it 10mm from the other hole. No the other hole. No, up not sideways. Wait, which way is up? Never mind, I'll do it myself." I'm having trouble understanding why you would want to do this. A good interface between what I want and the model I will make is to draw a picture, not write an essay. This…
Think about it this way, if the richest person in the world wanted something done, they would probably just shoot off a text to someone, maybe answer a few questions, and then some time later it would be done. That's your interface.

You would be amazed at how much time CAD users spend using Propriety CAD Package A to redraw things from PDFs generated by Propriety CAD Package B

#55Earlier quoted context omitted.
Here's how it might work, by analogy to the workflow for image generation: "An aerodynamically curved plastic enclosure for a form-over-function guitar amp." Then you get something with the basic shapes and bevels in place, and adjust it in CAD to fit your actual design goals. Then, "Given this shape, make it easy to injection mold." Then it would smooth out some things a little too much, and you'd fix it in CAD. The…
In your example, what about mounting the electronics or specifying that the control knobs need to fit within these dimensions? I guess its easy if those objects are available as a model, but thats not always the case.. 3d scanner maybe?
You'd get control knobs of a reasonable size, and mounting holes in an arbitrary rectangle, then correct them with the true dimensions outside of generation.

#56A recent Ezra Klein Interview[0] mentioned some "AI-Enabled" CAD tools used in China. Does anyone know what tools they might be talking about? I haven't been able to find any open-source tools with similar claims. >I went with my colleague Keith Bradsher to Zeekr, one of China’s new car companies. We went into the design lab and watched the designer doing a 3D model of one of their new cars, putting it in different c…
Happy to be corrected but this sounds like the kind of bullshit that crops up from time to time confusing "old" AI with generative AI.
Not that I don't believe it's possible. I just think the alternative (that it's bullshit) is more likely.

Sounds like he could have been using an implementation of stable-diffusion+control-net. I’ve used Automatic1111, but I understand comfyUI and somethingsomethingforge are more modern versions.

#58I get that CAD interfaces are terrible - but if I imagine the technological utopia of the future - using the english language as the interface sounds terrible no matter how well you do it. Unless you are paraplegic and speaking is your only means of manipulating the world.
I much prefer the direction of sculpting with my hands in VR, pulling the dimensions out with a pinch, snapping things parellel with my fine motor control. Or sketching on an iPad, just dragging a sketch to extrude is to it's normal, etc etc. These UIs could be vastly improved.
I get that LLMs are amazing lately, but perhaps keep them somewhere under the hood where I never need to speak to them. My hands are bored and capable of a very high bandwidth of precise communication.

#59I did this a few months ago to make a Christmas ornament. There are some rough edges with the process, but for hobby 3D printing, current LLMs with OpenSCAD is a game-changer. I hadn't touched my 3D printer for years until this project. https://seanmcloughl.in/3d-modeling-with-llms-as-a-cad-luddi...
As a MCAD user this makes me feel more confident that my skills are safe for a bit longer. The geometry you were trying to generate (minus bayonet lock, which is actually a tricky thing to make because it relies on elastic properties of the material) takes maybe a few minutes to build in Solidworks or any modern CAD package.

I spend a lot of time using proprietary CAD package A to redraw things from Who Knows What, but that's mostly because the proprietary CAD data my vendor would send me is trapped behind an NDA for which getting legal approval would take more time and effort than just modeling the things in front of me with minimum viable detail, or else my vendor is 2 businesses removed from the person with the CAD data that I need (and may require a different NDA that we can't sign without convincing our vendor to do the same). Anyone I've ever been able to request CAD data from will just send me STEP or parasolid files and they will work well enough for me to do my job. Often I spend more time removing model features so my computer will run a little faster.
