CAD thatcannot fail.AI-native.
No failed booleans, no broken fillets, no feature tree to repair. FieldCAD models geometry as a signed-distance field, so the operations that crash conventional CAD mathematically cannot fail — and the whole kernel runs in your browser tab, no install.
Describe the part. The AI builds the field.
The assistant is not a chatbot bolted on the side — it reads and writes the design graph itself. Name the interfaces, loads and process; it composes the operations and grades the fields. Every AI edit lands in the graph like your own: reviewable, parameterized, reversible.
Because geometry is a field expression rather than a mesh, the AI works in the same language as the kernel — it edits the model, not a picture of it.
Included on every plan: paste your own Anthropic API key and the assistant runs in your browser, on your account. The key stays on your device and is sent only to Anthropic — never to FieldCAD.
Every demo is a real document, not a picture. Click one and it opens in the editor.
The demos are coming online — the first documents land with launch.
Not a B-Rep. A field.
A B-Rep solid is a stitched shell of trimmed faces held together by tolerances. FieldCAD stores no boundary at all — union is min(f₁, f₂), subtraction is max(f₁, −f₂). No surface-surface intersection, no trimming, no sliver faces. The B-Rep failure modes have no analogue here.
