I appreciate that you have given this some thought, but it is clear that you dont have much or any professional experience in 3D modeling or mechanical design.

For the guitar amp, ok. Maybe that prompt will give you a set of surfaces you can scale for the exterior shell of the amp. Because you will need to scale it, or know exactly the dimensions of your speakers, internal chambers, electronics, I/O, baffles, and where those will all ve relative go eachother. Also...Do you need buttons? Jacks/connectors/other I/O? How and where will the connections be routed to other components? Do you need an internal structure with an external aesthetic shell? Or are you going to somehow mold the whole thing in one piece? Where should the part be split? What kind of fasteners will join the parts and where should they be joined? What material is the shell? Can it be thinner to save weight? Or need ribs or thickness for strength? Where does it need to be strong?

These are the issues from 30 seconds of thinking about this. AI (as suggested) could maybe save me from surfacing an exterior cosmetic cover, given presice constraints and dimensions, but at that point, I may as well just do it myself.

If you have a common, easy, already solved an mechanical design problem (hinge e.g.), then you buy an off the shelf component. For everything else, it is bespoke, and every detail matters. Every problem is a "wine glass full to the brim"

I think you’re jumping too fast to the “vibe CADing” extreme. It’s been a while since I’ve used Solidworks in anger so I’d rather use ECAD as an example: I’d kill for the ability to give Altium a PDF datasheet and have it generate footprints or schematic components tailored to my specific pinout for a microcontroller. Or give it a pdf of routing guidelines and have it convert those to design rules tied just to those nets. Those are the details that take up most of the time (although I’d still spend quite a lot of tine verifying all the output).

In MCAD it’s less of a problem because all the big vendors like Misumi, McMaster, et al have extensions or downloadable models but anything custom could probably benefit from LLMs (I say this as someone who is generally skeptical of their vision capabilities). I don’t think vibe CADing will work because most parts are too parametrized but giving an AI a bunch of PDFs and a size + thickness is probably going to be really productive.
