I wanted to create some cad software for my self so I decided to give it a go with Fable and see what it could do. One shot - make me some cad software that I can import and export to my 3d printer. At first, the software looks extremely impressive,… when I started using it there were a ton of features missing. No problem, I can vibe code and give it more direction to add in the missing features so it looks more like an onshape with parity. At first the features looked ok, but then as I added more the feature quality degraded more and more. Model parts are not anywhere close to where they should be, the geometry is totally messed up. I keep asking fable to fix the bugs, but it honestly can’t fix it. It seems like fable doesn’t have the visual understanding to make this type of application work. I think from a stand point of being truly involved in the code and having fable write specific algorithms and building that up to create the feature I want, is the process that is still required. But this is basically getting back to the same capabilities that opus had. I’m not saying this stuff is bad, but I am saying Fable seems overhyped and I just don’t see the step function quality improvement over opus. The only difference is that opus 5 is way more verbose and gets stuck on details that are not important. Fable works the way I want opus to work. For now I think I have to micromanage the model until they get better, but I’m extremely skeptical at this point that anyone can be hands off in development,… especially anything technical with important math simulations and quality. Is anybody else experiencing the same thing? submitted by /u/DopeyDonkeyUser
