🚀 Gemini 3.1 Pro vibe-coded a double wishbone suspension • Independent double wishbone design • Dynamic coilover shock absorber • Vented disc brakes with performance caliper • Real-time kinematic travel & steering simulation AI isn’t just generating visuals anymore!

@JeffDean the jump from "generates a 3D model" to "generates working physics sim" is actually wild. means it's reasoning about force vectors and travel constraints, not just pretty shapes.

@JeffDean

This is not CAD, it is actually just visuals. Not every 3D visualization is CAD.

wrong. this is CAD. everything ist paremetrized.

@jordannoone Then what are the underlying file types. Like is it B-REP, is it mesh? How is the state of the object represented during creation, modification and storage? Will the file remain consistent from user to user?

@jordannoone there are different CAD engines. Each has its own file type. My software is online. So no files. Like Onshape. All are online projects. Full parametrized. You can export as Ifc, Step.

Would you be willing to share the link to this work or the production process?

@xydavechen nothing special about the development process. Just vibe coded in google's ai studio

Incredible.

Amazing!! I did a Fusion add-in ... must try it with Gemini!

@JeffDean What’s the prompt you start with?

wait what? @grok what do we see here.

Just wait until we can do this with solidworks.

@grok what publically traded company stocks are most likely to benefit from this capability?

ai out here designing car parts while i’m still debugging print statements

let the AI debug it for you ;)

@grok for CAD what software is being used here?

If this can be implemented conveniently, it will change the mechanical design industry.

I am working on it. In my opinion traditional CAD is dead as traditional software development.

Vibe coding a full double wishbone suspension with real time simulation is next level. AI building engineering tools from a single prompt is insane

Do you admire you even more after reading it? How did this happen? It‘s really incredible. Can AI do this?

Steering is backwards

👏🏻👏🏻👏🏻👏🏻

Is this a full little wrapped web app it made or can it export worthy STEP files?

i could add step export.

I’m curious the sim you’re showing. Is that prompted to that one part? And are you showing more that it can create a sim or that it can model CAD objects accurately ?

Dang. That's really cool.

cool

vibe coding mechanical engineering is wild. domain knowledge + AI is where it gets actually useful. someone who understands suspension geometry using this will go further in an hour than a pure coder going in blind for a week

this is so amazing

could you please share the prompt

Insane

is there a online working prototype?

We went from “AI can draw a car” to “AI can redesign the car.” 😄

RIP Mechanical engineering and draftsperson

@JeffDean the fact that ai can now vibe-code mechanical engineering designs from natural language is wild. we went from 'ai can't understand physics' to 'ai designs actual suspension systems' in like 18 months. embodied intelligence through code generation is the real sleeper breakthrough.

for what purpose to generate this? can it simulate a car?

Valid: AI moves from visuals to physics. Reframe as engineering partner. Appreciate the CAD viewer. Progress is rapid. Keep pushing

I know it's early, but this design is rubbish, at least from a mechanical engineering practical perspective and all more. But it's in the direction.

it took me 90minutes without much attention from nothing. I am not an suspension expert. only 5 month ago it was so primitive: extrapolate. AI will design completely new stuff based on first principles (physics, chemistry) soon.

what is that ? code for what software? one shot?

How do we take exisitng CAD models and replicate this functionality for parameters? Thoughts?

You have to develop agents for each software. Unfortunately CAD kernels are not open.

@bpranav6 Well, there is OpenCascade. And the licensed solid kernels like Parasolid have an api surface. You do need a proper domain model ofc to get anyhwhere. I’m not familiar with mecheng but at least in AEC eg Tekla Structures has a well documented API that allows designing a building.

@bpranav6 OpenCascade is slow. Parasolid expensive. And data is hard to transfer. Often only via static step.

Would you mind sharing your prompt?

it is more than one prompt. created in google's ai studio

@robin7331 Its more than 1000000 prompts with more than 100 engineers/ui experts/products that worked on it

@daniel_z1909 Sure.
