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.

How it works

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.

01 · Describe

Brief it in words

Type the part and its dimensions the way you'd hand it to a colleague.

02 · Generate

It plans the features

OrionFlow lays out sketches, pads, pockets and patterns — a parametric tree, not a static mesh.

03 · Edit & export

Change a number, rebuild

Tweak any parameter and regenerate. Download STEP, STL, or GLB.

Built for real work

Engineering-grade, not a toy renderer.

Parametric

Editable feature history

Sketches, pads, pockets and patterns you can reopen and re-dimension — geometry stays driven by parameters.

Constraints

Constraint-aware sketches

Profiles carry their dimensions and relations, so an edit moves what it should and holds the rest.

Fidelity

Deterministic round-trip

A model rebuilds to the same solid every time — verified, not approximate.

Exports

STEP · STL · GLB

Take the solid into your CAD, your slicer, or the browser — standard formats, no lock-in.

Topology

Stable references

Faces and edges are pinned by geometry, so edits survive instead of breaking on a renamed face.

Open core

Build123d + FreeCAD

Standing on proven open kernels — your models aren't trapped in a black box.
