Fornjot is an early-stage boundary representation (b-rep) CAD kernel written in Rust, designed as a foundation for building code-first CAD tools and applications. The project has been shut down and its goals were never reached, though the code remains usable for very simple models.

Use cases

• build a code-first CAD application in Rust
• define 3D models programmatically with b-rep geometry
• experiment with CAD kernel internals
• create simple models for 3D printing
• integrate a CAD kernel into a game or graphics engine

When to choose

• you want to study or fork an experimental Rust CAD kernel
• you only need very simple code-defined 3D models
• you're building a research or hobby CAD experiment

When to avoid

• you need a production-ready CAD kernel for real-world use
• you require advanced modeling features or reliability guarantees
• you want a maintained project with active development
