What is reverse engineering?

Reverse engineering is the process of turning a physical part into a fully editable CAD model by capturing its geometry (via 3D scan), cleaning and reconstructing the mesh. It’s ideal for undocumented or obsolete components where no original CAD data exists.

Why reverse engineer?

Legacy Parts Reproduction: Many critical components, especially in aerospace, automotive or industrial machinery, are no longer in production. Reverse engineering lets you recreate these parts exactly, restoring functionality without needing original drawings. Tooling & Fixture Design: By capturing an existing part’s exact geometry, you can design jigs, fixtures or molds that fit perfectly, speeding up setup times and ensuring repeatable accuracy. Spare‑Parts Manufacture: Small batches of specialised parts (e.g., custom fasteners, machined brackets) become cost‑effective when you can scan and print or machine them yourself.

How does your reverse engineering service work?

3D Scanning: We capture your part’s surface with ±0.03–0.05 mm accuracy. Mesh Processing: Raw point‑cloud data is cleaned, holes are filled and a watertight mesh (.STL/.OBJ) is generated. CAD Recreation: Expert modelers rebuild surfaces as parametric solids in STEP, IGES.

What part sizes and geometries can you reverse engineer?

We handle everything from small precision parts (< 50 mm) to large assemblies (several metres). Portable scanners let us perform in‑situ capture of fixed equipment, while our desktop systems excel at fine‑detail components.

What deliverables and file formats do you provide?

Editable CAD models: STEP, IGES Optimised mesh: STL, OBJ Inspection reports: PDF with deviation maps and dimensional call‑outs 2D drawings: DWG or PDF (optional) All outputs are delivered via secure download link.

How long does a reverse engineering project take?

Simple parts: 7–10 working days Complex or large assemblies: 15–20 working days Rush services can often be accommodated; just let us know your deadline.

Can you modify or optimise the design during reverse engineering?

Yes. Our CAD recreation process can incorporate design improvements, wall‑thickness adjustments, weight‑reduction features or added mounting points, and we document any changes with revision history for full traceability.

Do you sign NDAs or confidentiality agreements?

Absolutely. We understand the sensitivity of proprietary designs. Monolith Performance will sign your NDA or work under our standard confidentiality agreement to keep your IP fully protected.
