Mechanical CAD Engineering

We reverse-engineer the parts no one makes anymore.

CAD modeling, technical drawing, and simulation for classic and race cars whose original components no longer exist.

Capabilities

What actually happens on your project.

CAD Modeling

Every part measured or scanned, then rebuilt as a fully-toleranced 3D model — ready for machining or the archive.

Product Drawing

Manufacturing-ready technical drawings — GD&T, tolerances, material call-outs. The documentation the factory lost.

Simulation

Stress, thermal, and fit simulation before a single part is cut, so the reproduction performs like the original — or better.

Focus — Classic & Race

Discontinued by the factory.
Not by us.

Right now, the studio is dedicated entirely to one problem: components for classic and competition cars that have outlived their parts catalog. If it no longer exists on paper, we put it back on paper — then back on the car.

Process

Three ways to get your part back into production.

Every project starts with the same question: how do we get the geometry from your workshop into our CAD system? Pick the path that fits your timeline, tolerance needs, and how much of the part you still have.

Remote Capture

You send photos & measurements. We do the rest.

Fastest Most affordable You shoot & measure
  • Fastest turnaround — no shipping, no scheduling.
  • Lowest cost — you only pay for engineering time.
  • No risk of damage or loss in transit.
  • Dependent on your photo quality and measurements.
  • Limited to simpler geometries and visible features.

Ship Your Part

Send us the original. We scan, model, and ship it back.

Best accuracy Recommended Pack & send
  • Highest accuracy — sub-0.05 mm in a controlled environment.
  • Works on any geometry — curves, threads, fine details.
  • We handle scanning, modeling, and safe return.
  • Part is away for 2–3 weeks including transit.
  • Not ideal for very large or heavy components.

From drawing to finished part.
Handled end-to-end.

We are building a network of trusted local manufacturing partners so you never have to chase quotes, compare tolerances, or worry about shipping. You send us the part or the drawing — we handle contact, sourcing, technical communication, and delivery. Technical drawings, geometric tolerances, material specifications, and shipping: all managed through Retroneering.
