CATIA
Lab Curriculum.

BUG FOUND: designers who can model a part, but cannot fix a model that cannot be manufactured.

$ step-01 brushup // weeks 1–2 — Topics taught:

1. CATIA sketcher basics: constraints, dimensions, and fully defined sketches.
2. Part design: pads, pockets, fillets, and chamfers.
3. Assembly basics: constraints, mates, and interference concepts.
4. Drawing basics from a 3D model.
5. Feature history: why order matters, and how a broken reference propagates.
6. Manufacturing basics: tolerances, draft, and wall thickness.

$ step-02 debug // weeks 3–4 — Production Debugging. Tools: CATIA, sample parts and assemblies, interference checks.

• BUG #1: Design defect: a part interferes in assembly — find the feature cause, fix it, prove zero interference.
• BUG #2: Manufacturing-unfriendly feature: a thin wall / sharp internal corner — redesign for manufacture, document the change.
• BUG #3: Broken references after an edit — repair the feature tree without rebuilding the whole part.
• BUG #4: Drawing does not match the model — find the outdated view / dimension, update it, verify.

$ step-03 navigate // weeks 5–7 — Codebase / System Navigation:

• Navigate assemblies and parts: trace a defect to its feature history.
• Fix a defect without breaking the assembly: check mates, references, and downstream drawings.
• Audit a model for tolerances, draft, and manufacturability; list every issue by severity.
• Review a peer's model change for assembly impact and manufacturing risk.

$ step-04 ship // weeks 8–9 — Shipping Features: capstone — a corrected 3D model with a manufacturing note, presented as if to a manufacturing reviewer.

$ ship → PROOF — exact output: corrected 3D model, manufacturing note, and an interference-check report.
