Show HN: SolidCraft – Open-Source Parametric CAD in Rust (With MCP Support)

People don’t get the super high value proposition in having these all *Craft packages controlled (automated) by AI. Most of the companies who are the kingmakers in the given area, do not allow it easily or are hard to integrate (costly) with, or did allow back in time and don’t now.

Given much can be automated in 2026, these (promoted goodies) may come as the missing link in innumerable automation chains, and particularly where commercial agents aim for when they sell costly licensing.

It also indirectly fights piracy and the risks which come with pirated copies (sidelined with funny stuff).

Looks like this uses the Truck modeling kernel: https://github.com/ricosjp/truck

Interestingly, ttouch created browser-based CAD tool CADmium a few years ago based on Truck. Then, a few months ago, they created another one (CADara) based on OpenCASCADE: https://news.ycombinator.com/item?id=48070083.

Truck seems cool, but creating a b-rep kernel is a phenomenal amount of work. Given that, I'm curious how quickly SolidCraft will mature.

Very interesting. Looking at the images I'm not sure if this is based on Autodesk Inventor (plausible since they already imitated AutoCAD), or in Solid Edge (given the name).
