How we're building it.
Notes on the representation, the data, and the engineering behind editable parametric CAD.
-
A kernel-independent IR for editable CAD↗
Why every OrionFlow model is a FeatureGraph first — one representation that compiles to FreeCAD and build123d alike.
-
Teaching a model to think like a CAD engine↗
Multimodal extraction: feature graphs, rolling geometry, sketch constraints, and topology-stable anchors as training signal.
-
Deterministic round-trip, verified↗
How we prove a generated model rebuilds to the exact same solid — down to the cubic millimetre.
-
Beating the Topological Naming Problem↗
Replacing fragile face IDs with geometric coordinate signatures, so an edit doesn't break on a renamed face.
