How scan-to-CAD works

A simple three-step workflow that takes your physical part to a clean, editable CAD file.

01

3D scan the part

We capture the full geometry of your physical part with structured-light and laser scanning down to ±0.1 mm accuracy.

02

Mesh cleanup & alignment

Raw point clouds are decimated, aligned, and converted into a clean, watertight reference mesh suitable for modelling.

03

Parametric CAD modelling

Our engineers rebuild the part as a fully editable parametric CAD model with proper features, datums and design intent.

From physical part to editable CAD

A simple three-step workflow that takes your physical part to a clean, editable CAD file.

On-Site 3D Scanning

Reflective reference targets applied to a truck cabin for large-format structured-light scanning. We scan parts in place — on vehicles, machinery, or assemblies — down to ±0.1 mm accuracy.

Raw Scan Mesh

A cleaned, watertight polygon mesh captured directly from the physical object. This mesh preserves every curve and embossed detail — the reference geometry our engineers use to rebuild parametric CAD.

Parametric CAD Rebuild

Rebuilt as a fully editable parametric model in Autodesk Inventor with proper features, sketches, and design intent — ready for engineering changes, drawings, and manufacturing.

When to use reverse engineering

Real-world situations where a scan-to-CAD workflow saves time, cost, and risk.

Obsolete parts

Recreate parts that are no longer manufactured or sourced from suppliers that no longer exist.

No drawings available

Reverse engineer legacy components when original CAD files and 2D drawings are missing.

Replacement parts

Produce drop-in replacement parts for machinery, equipment, and out-of-production assemblies.

Design improvement

Use a working part as the starting point to optimise geometry, weight, or material.

Fit to existing assembly

Capture mating surfaces and interfaces so a new part fits perfectly into the existing assembly.

Competitor benchmarking

Digitise competitor products to analyse construction, tolerances, and design choices.

File formats & deliverables

We deliver in whatever format your engineering team works in — parametric CAD for design and manufacturing, mesh for printing and visualisation.

Scan-to-CAD vs CAD design — which do you need?

Choose scan-to-CAD when you have a physical part. Choose CAD design when you are starting from an idea.

Scan-to-CAD & reverse engineering FAQ

What's the difference between a mesh and a parametric CAD file?

A mesh (STL/OBJ) is a static surface made of triangles — great for 3D printing or visualisation, but not editable. A parametric CAD file (STEP, SolidWorks, Fusion 360) is built from features and dimensions you can change, which is what engineering, drawings, and manufacturing require.

Yes — that is one of the most common reasons clients come to us. We scan the physical part, reconstruct the geometry, and rebuild a clean parametric CAD model from scratch, even when no original drawings or CAD files exist.

Our calibrated structured-light and laser scanners reach ±0.1 mm on suitable parts. Final achievable accuracy depends on part size, surface finish, geometry, and whether tolerances are critical features or general surfaces.

Parametric CAD: STEP, IGES, native SolidWorks (.sldprt/.sldasm), and Fusion 360. Mesh: STL, OBJ, PLY. We confirm formats up front so the deliverable plugs straight into your workflow.

Our standard scan-to-CAD turnaround is 2 business days from receiving the part. Complex assemblies and high-feature-count models can take longer; we confirm a schedule with your quote.

Pricing is quoted per project based on part size, complexity, required tolerances, and CAD detail. We give a transparent fixed quote up front so there are no surprises — request a quote with photos or the part and we will reply with a written scope.
