• 📌 What kinds of shapes can it make right now?
  Six families: - NACA 4-digit aerofoils (e.g. NACA2412 wing 200mm chord 600mm span) - NACA morph wings — interpolates two profiles along the span (NACA2412 to NACA0009 mor…

• 📌 How do I use the AI shape generator?
  Open the tool (cncfoam.com/), look in the top header for the purple ✨ AI button. Click it. A small dialog opens with a text input and six example chips. Click an example…

• Is this a real LLM (Claude/ChatGPT) behind it?
  Not today. The current version is purely procedural — it's pattern-matching regex against your prompt, picking the right recipe, plugging in your numbers, and outputting…
  ❤
• Why doesn't my prompt work?
  Most common reasons: 1. The shape family isn't supported yet. See the list above. If you typed "crown moulding" or "saddle" we don't have a recipe. 2. You used imperial.…

• Does it work offline / can I use it without an internet connection?
  The generator itself runs on cncfoam.com's server, so you need internet to reach the page. BUT — there's no third-party AI service in the loop, so we're not at the mercy…

• Can I save and publish an AI-generated shape?
  Yes — exactly the same way as any other shape. After generation, click 📤 Publish in the top bar, fill in the title/description/category/kinematics, and submit. Admin appr…

• How does the NACA aerofoil math work?
  Standard NACA 4-digit formula, untouched since NASA TR-460 (1933). A 4-digit code like 2412 encodes: - digit 1 = maximum camber, as a percentage of chord (here: 2%) - dig…

• What is a morph cut and why does the AI generator always produce one?
  A "morph" in foam-cutter speak means the wire follows a DIFFERENT 2D profile on the left tower vs the right tower. The wire is straight, but its endpoints trace independe…

• Can I request a new shape family / recipe?
  Yes please. Two options: 1. Post here in the AI-helper category. Tell us what shape you want, what 2–4 input parameters would describe it (e.g. for a Greek column: diamet…

• What about the original prompt — is it saved anywhere?
  Right now: the prompt you typed shows up briefly in the status pane (the line at the bottom of the simulator: ✨ NACA2412 wing — 200 mm chord × 600 mm span) and gets added…
