AI for mechanical engineers.
Describe a part in plain English. OrionFlow builds an editable, parametric model — not a frozen mesh — that you can re-dimension and export.
Watch a real part build itself →
From a sentence to an editable model.
Every model is a feature history you can open, change, and rebuild — the same way you'd work in CAD.
Brief it in words
Type the part and its dimensions the way you'd hand it to a colleague.
It plans the features
OrionFlow lays out sketches, pads, pockets and patterns — a parametric tree, not a static mesh.
Change a number, rebuild
Tweak any parameter and regenerate. Download STEP, STL, or GLB.
Engineering-grade, not a toy renderer.
Editable feature history
Sketches, pads, pockets and patterns you can reopen and re-dimension — geometry stays driven by parameters.
Constraint-aware sketches
Profiles carry their dimensions and relations, so an edit moves what it should and holds the rest.
Deterministic round-trip
A model rebuilds to the same solid every time — verified, not approximate.
STEP · STL · GLB
Take the solid into your CAD, your slicer, or the browser — standard formats, no lock-in.
Stable references
Faces and edges are pinned by geometry, so edits survive instead of breaking on a renamed face.
Build123d + FreeCAD
Standing on proven open kernels — your models aren't trapped in a black box.
How we're building it.
-
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.
