The copilot is the magic. The substance underneath is a real engineering stack — a native CAD kernel compiled from source, true B-rep solids, real NURBS, and real FEA on the parts you actually design. Inspect every layer: the kernel, the math, and the model weights are all open source.

Most text-to-CAD asks you to trust a screenshot. This page does the opposite — every claim below is a checkable fact, and the kernel, the math, and the model weights are all open for you to read.
A real kernel, compiled from source.
ArchDisc geometry lives in forge-kernel.node — OpenCASCADE 7.9.3 built natively in C++, with no WASM in the geometry path and no browser sandbox tax. The same class of B-rep kernel production CAD runs on.

Read it yourself — the kernel binding and OCCT build live in the open repo.
section A–A · counterbored, filleted hole · real Ø / R / ± and a GD&T feature-control frame, drawn by the kernel — not faked.
Real math, shown as value — never color.
Linear-static, modal, thermal, buckling, and fatigue analysis — with contact — run on the exact solids you design. We render results as greyscale density and contour, never a marketing rainbow, because a real plot doesn't need one. Archie can build a part, simulate it, read the result, and propose a fix.
greyscale density · iso-bands + contour lines · value, not hue
LINEAR-STATIC
Stress and deflection under steady load.
MODAL
Natural frequencies and mode shapes.
THERMAL
Steady-state heat and gradients.
BUCKLING
Critical loads and instability modes.
FATIGUE
Cyclic life against the stress history.
Same solids in, real fields out. No false color, no estimate.
Real scale, organized — not confetti.
Industrial assemblies past one hundred thousand components — racks, machine rows, tank farms — packed into zoned structure with real mates and live spatial queries, and they stay responsive. Scale you can navigate, not a polygon dump.

Built to be made.
Native B-rep means the solid leaves cleanly. Read and write STEP, IGES, DXF, glTF, and STL — both directions, no lossy re-import — so your model opens in SolidWorks, NX, Creo, or Fusion and goes straight to a shop.
Every operation Archie calls is a real kernel feature — editable, exportable, and built to be made.
feature-control frame + datum — real drawings, real tolerances, manufacturable.
Every solid is verified before you see it.
Archie doesn't hand you raw output. A coherence gate runs checkValidity() on the topology and self-corrects if something's off — so what reaches you is a valid solid with an editable feature tree, not a script you have to debug.
Open code. Open weights. Yours to run.
- Open code
- Read every line — the kernel, the app, the model harness.
- Open weights
- Archie's per-discipline fleet ships with weights you can run.
- Self-host

- Public release soon
- Pre-release today — star the repo to follow the launch.
See the geometry for yourself.
A native CAD kernel, real B-rep solids, real FEA — and open weights and code you can read end to end. AI-native, never approximate.
