When ever I see CAD mentioned on hackernews it's always 3D and never the more ubiquitous (in the construction industry) 2D documentation CAD. I wonder if this would be able to generate 2D vector files.
- huytersd 3y agoIt’s trivial to take a 2D image DALLE3 or midjourney generate and vectorize it (illustrator etc.)
- dheera 3y agoThat kind of vectorization is a royal pain to edit.
- cyanydeez 3y agoinkscape is pretty go at everything except simplification.
- fouc 3y agothat's not really suitable for the manufacturing/building route
- ben_w 3y agoIf you're getting your engineering plans from Midjourney etc., something is likely to explode.
- cm2187 3y agoTo be honest from the sample prompts they provide you would be lucky if any two pieces fits together.

- ben_w 3y agoProbably the Winchester Mystery House: https://en.wikipedia.org/wiki/Winchester_Mystery_House https://en.wikipedia.org/wiki/Winchester_Mystery_House That or gothic cathedrals: https://en.wikipedia.org/wiki/Gothic_architecture https://en.wikipedia.org/wiki/Gothic_architecture
- rdlw 3y agoIt's like the joke about the group of engineering professors who were invited to fly in a plane. After they get comfortably seated, they are informed that the plane was built by their students. All but one jump out of their seats and immediately run for the exits. Later, the lone professor who remained calm was interviewed, as he clearly had more confidence in the ability of his students than any of the others. “It's true, I know my students' ability very well, and I can tell you for a fact this plane won't move an inch.”
- huytersd 3y agoDepends on what it is. I use DALLE3/midjourney to give me ideas for furniture pieces all the time and then build them. This is obviously not as complicated as a CAD for a building but it’s still a great starting point.
- 1-6 3y agoA machine should be able to interpret topographic lines and generate an architectural floor plan that minimizes cut and fill.
- fouc 3y agoI've noticed the same problem, no LLM to manufacturing/construction CAD yet as far as I can tell? It would be nice to feed the LLM a set of dimensions, constraints, desired features, etc and have a few different versions generated. Quickly explore the problem space of designing house for a piece of land, or for 3d printing.
- 1-6 3y agoThe gateway to 3d cad is a properly functioning 2d cad system. At least, that’s how I view 3d. At the very least, the tool should be able to do additive and subtractive operations (boolean). Union, add, subtract, intersect, etc.
- BillyTheMage 3y agoThe way I see it, 2D is inherently included in 3D CAD, but 2D CAD is limited it's 2D-only nature. Parts physically exist in 3D CAD. When you're working on your blueprint, it's done more-or-less by performing the operations on the part that will be performed when it's manufactured. Every 2D view you could ever want is inherently included in a 3D part. But 2D... it's not much better than sketching by hand on a piece of paper. Everything's disconnected. You can forget to add a feature to a view, you can make mistakes between views. With 3D if you add a new flange or a hole or whatever to a part, every drawing is instantly updated.
- iancmceachern 3y agoThey're one and the same. We use 3d CAD to generate 2d drawings, that's the standard way 3d cad is used, to generate 2d drawings that let you make stuff. Many people get 3d modeling like for games or computer graphics confused with CAD, which is different. CAD is fundamentally 2d and 3d in nature both, as a function of how we use it to make parts
- kragen 3y agoi've definitely used 2-d cad programs that can't handle 3-d, and 3-d cad programs that are at best anemic for making 2-d drawings they're not one and the same, although some programs are capable enough to do both
- liotier 3y agoThat a CAD program can only handle 2D doesn't mean that it doesn't describe 3D. Even when plans where physical large format blueprints, 2D, the product they described was of course always 3D. In French, the draughtsman was called a "dessinateur projeteur" - as projecting the 3D objects to a 2D plane (the plan !) was his core skill.
- iancmceachern 3y agoExactly, because the end result is a 3d object in the real world that needs to function with its surroundings in 3d space. How we write down that shape to communicate it to eachother doesn't matter so much. It's like language vs content
- BillyTheMage 3y agoSeems like a massive waste of time to me, like hours vs seconds kind of waste of time. With 3D CAD, if I have a top view of a part and want to add a side view, it's like 3 clicks to just... make it exist. All views are derived from the 3D part/assembly, there's no effort needed to make new views pop into existence. Maybe I'm out of date on 2D CAD knowledge, but from what I remember you'd literally have to re-sketch the entire part for the new view. Because it's drawn in 2D, you can't just "flip it on its side" like you can a 3D part. And then you have to make sure you actually sketched the part correctly and didn't forget anything. I see it as analogous to programming with toggle switches.
