Reverse-engineer any part with AI.

OriginShape builds Oscar, an AI copilot for reverse engineering. Oscar’s AI agents read a 3D scan like an engineer. They rebuild the part, feature by feature, as CAD that you can edit and export as STEP. They flag anything uncertain for review. Oscar runs in your browser and in FreeCAD, and uses two AI models, Origin1 and Origin1 Super. Oscar is patent pending. OriginShape launched Oscar on 26 October 2026. You can use it at app.originshape.design.

Oscar builds parts from sketches, pads, pockets, revolves, grooves, holes, fillets, chamfers, shells, drafts, lofts, sweeps, threads, and patterns. That covers most machined and turned parts: shafts, brackets, housings, plates, flanges, and legacy parts with no drawings. For castings, forgings, and plastic parts, check the drafts and fillets that Oscar proposes. Sheet metal parts come out as solids, without a flat pattern. Oscar does not fit freeform surfaces to a scan yet, so check freeform shapes on the deviation map. The example on this page is a 120 mm stepped shaft.

Oscar builds the model from explicit, editable dimensions, not from a wrapped mesh. Change a diameter and the geometry updates. You can read the script that builds the model, and you export STEP geometry. In the example, Ø36.00 mm is the parameter d2.

Converters copy the scanned surface together with its wear and noise. Our AI agents rebuild the intended design instead. They flag anything uncertain for review and do not average it into the model. In the example, the scan becomes one revolved solid with 3 diameters and a 21.80° taper.

Oscar works from a mesh in STL, OBJ, PLY, or 3MF format. Laser scanners, structured-light scanners, and CT systems can export these formats. If you do not have a scan, send us the part. We will plan the capture with you.

Oscar delivers a parametric model with named dimensions, STEP and STL files, and the evidence for each key dimension. It can also make an engineering drawing and an inspection report that compares the model with the scan. STEP imports into SOLIDWORKS, Siemens NX, Autodesk Fusion, and Onshape. For the example shaft, that is 4 key dimensions: Ø24, Ø36 and Ø28 mm, and 120 mm overall.

Oscar runs in your browser. Oscar for FreeCAD builds the construction tree natively in FreeCAD 1.1 or newer. Oscar for SolidCraft works in SolidCraft’s Assistant panel, and we will publish it soon. Both plugins are open source. Plugins for SOLIDWORKS, Siemens NX, Autodesk Fusion, and Onshape come next. Until then, import the STEP file into those tools or into any other CAD tool.

A scan records the part as it is today, and wear can hide the original dimensions. We flag those dimensions and confirm them with drawings, extra measurements, or your engineering judgment. In the example, Oscar flags the shoulder position at z −35.00 mm for review.

Yes. Oscar uses two AI models, Origin1 and Origin1 Super. Oscar’s AI agents make each rebuild decision the way an engineer does. We check their output against a deterministic baseline. We judge accuracy on engineering criteria, not on the confidence of the AI models. The agents work in 4 steps: datums, design intent, features, and dimensions. In Oscar for FreeCAD, you can also use your own AI provider key or a local model.

Oscar is patent pending. We filed a patent application for Oscar, and the patent office has not decided on it yet.

No. We do not use your scans, files, prompts, or chats to train or fine-tune AI models. Our AI model provider processes your requests to write Oscar’s replies, and it does not train its models on them. In the app, you can download your data or delete your account under Settings.
