As someone who has used 3D CAD professionally for decades, I must confess I had low expectations for this tool. My expectations have been greatly exceeded, and there is real value in something like this. The value is not in creating models of new/custom parts, but in quickly generating models of standard parts such as pipe fittings, bolts, connectors, and stuff you could buy from a catalog. Prompts like "m4 cap screw…

Being able to output parametric models would be amazing. Much less interesting otherwise.

Thank you. Blender is definitely the wrong tool for this kind of job. It's a graphics tool, not a CAD tool. A drafter may use a pen, but that doesn't mean a calligraphy pen will do.

depends on what you're designing and what kinds of products you need out of your cad program

I'm intrigued, what kind of products do they design in Blender?

I'm inclined to believe that the people who make proprietary software are the ones with the "wrong worldview", if there is such a thing. People with morals are not the ones at fault for making the world parasitic to its core. You say you had to stop with the open source because you needed money. That has nothing to do with open source, and everything to do with the fact that you're not allowed to access the basic nec…

>the fact that you're not allowed to access the basic necessities of life if you don't allow yourself to be exploited for profit.

This is the underpinning of capitalism. Some people speculate that denying basic necessities is the only way to ensure that common people will be productive enough to make the wealthy people wealthier.

Disappointing to see Jessie Frazelle building closed source centralized tech. This approach mirrors "Open"AI sending all queries to central servers with no mention of any privacy measures. The admins surely get to see who is making sex toys, prop weapons, or medical parts and that data will be sold or leaked, as is tradition. This is a great idea though and I look forward to supporting whoever makes an open source al…

Good people are often swayed to do evil for the promise riches earned can do enough good to buy back their soul later.

Trouble is, the timing is never right to get out when there is always another payday just within reach.

These days I an happy to be paid to teach anyone anything but I have no interest in writing proprietary software anymore for any amount of money.

Everything I know and have built is because of FOSS and I owe that community my creations built on their work.

Is the site working? It accepts input, but the windows just show "Generating", even though the message "You are all caught up" appears.

Yeah it did that in FF for me. Chrome worked.

Oh. Why is it locked to Chrome?

Now it's totally broken:

This Serverless Function has timed out.

Your connection is working correctly.

Vercel is working correctly.

That 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.

Seems 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 t…

You are exactly right: 3D CAD has taken the draughtsman's job.

sorry, by 'products you need out of your cad program' i meant things like prints with dimensions and callouts, or stl files, or gerbers, not the physical artifacts those things are used to produce

Got it.

Same question, what are the products you are referring to?

i just answered that in the comment you're replying to, so you have exhausted the presumption of good faith, and this is my last comment in this thread

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.

They'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

I'm actually in the building construction industry and CAD generated 2D vector documentation is still the standard go-to for workshop and design drawings. Especially when it comes to contractors as-installed drawings. Some work had moved to 3D BIM modeling but often you'll still end up with 2D for a multitude of reasons and unless something drastically changes I don't see 2D work disappearing any time soon. Specifically because you can "show for calarity" in 2D more flexibly than with any 3D system because you are not modeling a space, you are documenting it.

You "could" generate 3D objects to use in a traditional CAD package but most of the time that would be overkill and just make your drawing, at best and un-editable and at worst a performance nightmare.
