B-Rep modeling engine for brepjs — pure Rust, compiled to WebAssembly

⚙️ Industrial-grade pure TypeScript STL ➔ 100% Watertight Solid STEP AP242 B-Rep & CAD Features JSON engine with built-in MCP server for AI agents. Features exact Gauss-Mirtich 3D inertia, ISO threads (M2–M24), boundary unification (no extra lines), Zero-GC speed, DWRR concurrency & 5-gate RSVS reality verification across macOS, Linux, and Windows.

Vibe-CADing: Conditional CAD Generation and Retrieval for a Text-to-CAD Design Pipeline

Browser-first parametric CAD: exact B-rep solids on a WebAssembly kernel, replayable feature history, direct on-model editing, STEP in and out. Local-first, with optional cloud projects and live collaboration.

MCP server for AI-assisted STEP CAD inspection, geometry queries, PMI hints, and revision comparison

Exact b-rep CAD kernel in pure Rust

B-rep solid modeling kernel in Rust: exact topology over tolerant geometry, with a decline-never-wrong contract.

Agent-native geometry kernel: a Rust B-Rep engine where every operation returns a validity certificate — nine structural invariants, computed under the write lock, failing closed. Outside its verified envelope it refuses with a typed error rather than approximating. The kernel cannot lie.

Plain English → exact, manufacturable CAD (STEP/B-rep). The LLM picks parts, params and mates; deterministic geometry and solvers do the rest — and it declines honestly when it can't build something.

Datum — Design Automation Toolkit for Universal Modeling. Parallel-first, deterministic B-rep CAD kernel in Rust.

Low dimensional topology and geometry.

C++ experiments in 3D geometry, graphics mathematics, CAD kernel concepts, and B-Rep data structures.

Grounded physical-world reasoning over product teardowns. Multimodal AI that understands why products are built the way they are, how they fail, and how to design them better.
