CAD that cannot 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.
Live — a graded gyroid raymarched in your browser · drag to orbit, scroll to zoom 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.

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.
