Mixed workflow with Claude, CAD and Houdini. Claude modeled the robot in Python using build123d. The model was then brought into Houdini, where Claude built an APEX rig. I blocked out a rough hand animation. Claude refined the timing and layered secondary motion on top. Lookdev and render in... Karma XPU. Claude is really good at writing Python CAD code. It follows instructions and references closely, and it’s very token efficient, barely using any tokens for the modeling part. I clearly see a strong hybrid workflow here for this kind of work.show more

can it stretch your back

haha yes!! 😅

claude doing an apex rig wasn't on my bingo card)) build123d to houdini is so clean

The build123d → Houdini handoff is the bit I’m curious about. Did the part structure survive the transfer, or did you have to sort that out again for the rig?

what exactly do you mean by that?

That's stunning - well done!

thank you!

did Claude do the secondary motion as keyframes or as a procedural layer in the APEX rig? procedural would survive you retiming the blocking

keyframes on this one

Now put it into Unreal and make a game where it destroys cities!

impressive! I was about to say there's now way LLM animated that :)

Very nice!

thanks!

Holy shit man

Amazing collaboration and effect

cool lol

My head is spinning))

Claude + CAD + Houdini 🔥 This hybrid workflow is the interesting part for me. AI handles the structured build, while the human still shapes motion, timing, and creative direction.

If this lind of robots that will invade human, I'm terrified

The token efficiency makes sense. build123d describes a part as a few operations on exact solids, so a whole leg segment is a few dozen lines where a mesh would be thousands of vertices. Bonus is it's real CAD, the same robot could go out as STEP and get printed

So cool! Why did you go with build123d and not something like OpenSCAD?

The Transformer architecture was originally invented to translate between English and German. As a consequence of this, it's not hard to intuit that as the models grow and generalize, any problem that can be effectively modeled as a "translation problem" is ideal for an LLM.

Imagine waking up at 3 AM and seeing that crawling across your bedroom floor. I'm throwing a shoe before I'm asking whether Claude wrote the Python code

Technically impressive. Also, nightmare fuel.

claude built the robot, rigged the robot and polished the animation. the human’s job was the rough pass and the “hmm, one more try”

Needs just a little bit more to be an actual Shoggoth Tekeli-li, the way a cat or dog probes and evaluates the environment.

i want that robot

Really understand very little of what you said but the results are cool.

thanks! its quite easy. claude used python to model this in CAD and then it brought it into houdini to rig and animate

How about basic legs and grabbers
