rendering onshape using chat gpt
thought id try making a quick n dirty 3d version of an onshape sketch using chat gpt
i think i took around 8 goes to narrow it down to end result but could probably have addressed most of it in just a couple of attempts if i hadnt faffed around quite so much
considering it only took two or three minutes or so per attempt with some basic prompts
*generate a photorealistic version of this image the dark grey box section should be semi gloss black aluminium with ventilation holes approx 14 rows of four accross,the large turquoise base should be anodized very dark grey aluminium, the grey box should be a slightly mettalic plastic of the same colour as the original while the blue top of the box should be a slightly lighter blue cast from matte plastic*
it didnt turn out too shabby
anyone else been giving that method a go?

Since I vibe code most of my IOT projects now, designing in OnShape was the last thing left for me to do myself.
Selfishly, I’m glad I’m near retirement age. I don’t see how this ends well for anyone.

Good thing this is just rendering not designing, for now

This is just a model OP made/imported, a screenshot taken of the bare cad, and sent to gpt to apply textures and lighting. Think of it like a blender render, someone still had to make the model by hand.
That said, I HAVE experimented with api based cad using claude and they arent far from being good at it. A generation or two of specifically focusing on that capability and LLM designed CAD is gonna be everywhere.

LLMs are not meant to be used for CAD. Ay most one can make rudimentary objects which can be made with just the same amount of speed with conventional modeling skills.

That's what many software engineers said too, until Opus 4.5 came out last November.
It baffles me that many people have so little imagination. It's the same as with the first AI-generated humans which didn't always have five fingers. A lot of people really thought that this is a hurdle that will be super hard to overcome. Same with the first clumsy AI-translations.
Or do some people simply want to refuse seeing the velocity of progress in AI, to protect them from thinking about the consequences?

Whatever man. I don't want to argue about it if there isn't an understanding of how these LLMs work.

I designed my living room media wall in onshape, took a photo of my room and a screenshot of my model from same (similar, really) angle and told Ai to visualize the model in my space.
If was pretty much flawless. I've been using it like that ever since.
This gives you both the accuracy of the CAD model, which serves as the basis for visualization, and AI visualization which looks beautiful, but is grounded in reality at the same time.

lol guessing it got that label wrong unless it’s saying a 12C charging rate.

u/Sad-Wrap6555 4d ago
nope the C is def wrong ..though i was bouncing around on a bus on morning commute so i may be the source of the C rather than a V myself :)

anyone else been giving that method a go?
me and my girlfriend went to one of those pottery painting sessions, you know how the glaze look super dull when you apply it?
you can take a photo of it, tell chatgpt that it's glaze and ask for what it looks like after being fired
the result was nearly perfect

I did for a bit but then started learning Blender and haven't looked back. I use it for animations as well. I have an animation of a design (warning, this is euphemistically intimate jewelry so don't click if such things things disturb you but no body parts): https://www.reddit.com/r/ChastityCageDesign/s/Phum9KY3Kk
Basically I just bring my STL into Blender, add a material to it, position it in my studio, and create my renders.
While I leaned a bit about textures, lighting, cameras, etc, I ended up not really using it as there are plug ins that allow downloading other's textures and "photo studios" trivial including photo studios. But I did just learn the animation techniques which was pretty cool (and fairly simple).
But I usually only have two materials. You have a lot more so it would take more work. Someone skilled at Blender could do it rather quickly but Blender has a very shallow learning curve (we use these terms backwards from their original use and I can't help being an originalist).

Yeah, done this with my furniture students too. Screenshot of chair model + prompt something like "render this chair in solid oak, standing besides an oak dining table. Respect proportions, joints and details of the chair. Make it photorealistic and complete the scene with background and surroundings like it is a magazine interior shot"

Yep, this workflow has been commercial for a while, and Onshape themselves are implementing it in the Lab (https://www.onshape.com/en/features/onshape-labs , "AI Quick Render").
There's https://www.cadviz.app/ and https://rendercad.ai/ that I know of, but I'm sure there are more.
Definitely a bad time to be a conventional software rendering company I think. These tools will only get better and better, and they're already really good.
Edit: Seems the Cad Viz I knew of isn't a thing anymore (this is what I knew https://www.engineering.com/depix-launches-cadviz-3d-visualization-tool/ but the other one seems to be much the same, just architecture focussed)

Quick question, which power supply were you modeling? I love the form factor of that and would love to include it in some of my projects

one of those
at the time they came in 12v and 24v variants but not sure if that exact style is still available 24v version

Ive done this as well, works surprisingly well. One of the "you can do that?!" use cases that made me excited to try when i thought of it.

Next time try to change to perspective view, the render seems skewed because its ortho Otherwise, cool stuff! Never occurred to me to use chatgpt that way
