A full-featured 2D + 3D CAD application built in Rust with GPU-accelerated rendering. Native DWG & DXF read and write, paper space, ACIS solids, dimensions, layouts. An open source community project by Hakan Seven, recognized and promoted by the OpenAEC Foundation.

Claude directly has over 1100000 lines of direct code contribution. It has pretty much the same amount of code committed directly as the creator has.
His entire coding history before Claude consisted of changing readmes or searching and replacing project name text or modifying a dead link to his own link.
Suddenly in 4 months, without ever producing actual code before, he becomes a very competent coder enough to tackle mCAD, a notoriously difficult coding task that takes many many years with teams to make meaningful progress on?
That is vibe coding.
And his co-contributer “gianlucafiore” is exactly the same story. Has literally only made issues until LLM coding got released and then late 2025 (December) switched to making commits that he badly copied from an LLM such that some of the commits are literally one full line (as direct in-file working of the LLM wasn’t as accessible then)
That is vibe coding.
So the top 3 contributes are
- An LLM
- Someone that only has committed any code via an LLM
- Someone who has only made issues before beginning with an LLM and submits clearly generated code
There is likely no human-made code in the entire project besides changing a couple links.
Holy shit
He did a great job, even with AI I will hope to donte to him
shame
Besides all the whining here, is the program actually good? Does it work? Is it buggy?
If people can create useful working open source software using LLM’s then I don’t really care an LLM wrote it.
While a steep learning curve, I think moving forward with cadquerry or other programming based approach will be the best way to future proof your cad workflow
I’m allergic to AI code. It’s worse than spaghetti. I wish it wasn’t AI-made, for the most part.
so you haven’t tried it.
Spaghetti is pretty good.
I have tried it, I downloaded it. But while it kinda works now, you can’t untangle AI code in the future. It becomes too complicated and difficult to debug. Any project that uses mostly AI, doesn’t have a future. It only has a temporary present, while things are still simple.
