SolidCraft
Parametric CAD in Rust for desktop, browser and AI agents, MIT or Apache
Emerged finds new products worth a look, daily — what’s new today
Sketch constraints, an editable feature history and STEP in and out, free under a permissive licence, and reachable in a browser with nothing to install.
A mechanical modeller written in Rust. Sketches run on a custom constraint solver; extrude, revolve, fillet, shell and patterns sit in a history you can go back and edit. Assemblies, sheet metal, STEP, STL and glTF import and export, a headless command line and an MCP server for scripts and agents. Installers cover Windows, macOS, Linux and FreeBSD, and a browser build needs no install. Dual MIT or Apache-2.0, about 13,000 stars and 3,700 commits since 7 October 2026. The README calls it early but usable for simple parts, with 75 of 76 reference parts verified. By Tangency Labs.
