Cadre Documentation

AI co-reviewer for parametric CAD. Model parts in the browser, then have AI flag manufacturability issues — thin walls, sharp internal corners, steep overhangs, small features, enclosed voids, non-watertight solids — and propose concrete parameter changes. AI suggestions and human suggestions arrive in one review inbox; you accept or discard each with one click.

Cadre runs in any modern browser with no install. Geometry is computed by a Rust/WebAssembly kernel and measured from the model itself, not estimated on screen.

What Cadre does

• Modeling — sketch, parametric primitives, and an editable feature tree with variables and expressions.
• Review inbox — one queue for AI and human suggestions, each accepted or discarded as a single reversible step.
• AI review — manufacturability flags grounded in the kernel’s measured geometry, with parameter fixes shown as old → new.
• Collaboration — presence, link sharing, and asynchronous fork-and-suggest review.
• Export & interop — STL, OBJ, STEP, 3MF, and glTF/GLB out; a shareable review link; a structured JSON review for tools.
• Measurement integrity — volume, surface area, and watertightness computed from the geometry as trust properties.

How it works, and why to trust it

• Architecture — the three properties that make outputs trustworthy: one geometry authority, one review pipeline, verified export.
• Methodology — the claims Cadre makes, and how you can check each one yourself.
• Trust & data — no-install, offline-capable, local-first, and what stays on your machine.
