Not convinced text-to-CAD will actually speed up productivity.
Engineers design things in their head way faster than they can come up with the exact words to constrain it.

Hard to get past HR’s throwing 98% of resumes in the trash at random

It’s currently: think in 3D -> CAD it
Text-to-CAD makes it: think in 3D -> figure out the words to describe it -> LLM won’t understand completely-> adjust text and repeat x number of times until it works -> CAD generated.
Not where I want AI to be in design process.

Funding (partially) secured!
Excited to say we are building a hybrid VTOL drone similar to the Anduril Roadrunner or SheildAI VBat.
Please reach out if you are interested in helping fund this project! We are looking to raise an additional $1-2k
Please retweet for visibility!
TAMU drone initiative:
Thesis: Drone competency is critical to the next decade’s geopolitics
Mechanical + aero goal: build a Mach 0.7 VTOL drone
CS + EE: build control ground system, swarming operations, automate operation
+ payload sub team
+ ground equipment sub team

How do y’all document all of your engineering work?
My current process is dumping everything into PowerPoint, making sections for each part of the project. I can control F everything if needed and prettiness isn’t a concern so it doesn’t slow me down.
Anything better?

Why robots? Flexibility. With two robots, we shape intermediate geometries, then we take it up a notch: forming, for example, a dome with zero draft angle, using method similar to spin forming but with one robot and no die. And what do we call it? You guessed it… Robospinning!

1) Everything is usually there for a reason.
2) If you don’t understand the reason and want to do away with it anyways alarm bells should go off in your head.
Understanding (like TRULY understanding) is the only way to make intelligent decisions.

I don’t know if this is text to cad tho it is something more
3d context could be really powerful- it’s really just text to cad /in isolation/ that doesn’t seem to be useful

How??? No one wants the AI equivalent of topology-optimized slop. I’m so bearish here I’m ngl. Anyone who has done engineering design knows it’s so complicated. So so complicated.
“Automating the design process” sounds like bubble-ish AI hype, but please, someone prove me wrong.
The CAD industry is on the brink of its biggest transformation in over 50 years. The third era is upon us and it will fundamentally reshape how we engineer our world. Let me explain...

I’m gonna say this nicely, because for some reason these guys come across as genuine and not grifters:
This is a Popular Mechanics level understanding of the problem. LRASM is big and expensive. It’s not that way for no reason./1

That’s what I’ve heard.
I wanted to test it and it just took me <1 minute to create a dimensioned sheet metal box with a chosen bend radius and material thickness. That included doc creation and loading.
I personally would never go to a different program to save 30s

In the age of AI X is one of the most valuable social media/companies. Where else do you get live text data about what’s happening in the world at every second of every day? And the xAI team he has built is cracked. IMO he looks like a mastermind rn.

So with the whole F=ma // E=1/2*m*v^2 // p=mv thing how fast are these things going to go???
My immediate reaction from a physics standpoint is that smaller isn’t better in this situation, unless it lets you go CRAZY fast

@Ares_Industries
(YC S24) is building 10x smaller and cheaper anti-ship cruise missiles.
Current offerings by the primes are too big, too expensive, and are made in low volume. Ares was founded to solve this problem.

Kinda crazy what happens when a market is proven.
So many rockets in this thread. Awesome.
This is Starship. It is a SHLLV capable of lifting over 100t to LEO reusably, refueling, and will be landing on the moon and Mars. Its primary duty is “internet constellation”

In case you are wondering (you know, for your online arguments), it takes an estimated 4-8 years to convert a port to full automation, and between $500 million to $2B.
For reference, Shanghai’s Yangshan port took about 4-6 years from conception to full operations.
