Reverse Engineering & 3D Scan to CAD

From Physical Part to Parametric CAD

You have a part — a legacy component, a worn-out spare, a supplier sample, or a hand-made prototype — and no usable CAD file behind it. We digitize the part and rebuild it as a native SolidWorks model you can edit, manufacture, quote, or improve. No drawing, no problem.

Reverse engineering is not tracing a shape. Every dimension we capture is checked against the part's function, its tolerances, and the manufacturing process that will reproduce it. The result is a model that behaves like a designed part — not a frozen scan mesh.

Core Capabilities

  • 3D Digitizing: Scanning and measurement planned around the features that matter — mating surfaces, fits, motion, and critical dimensions.
  • Point Cloud & Mesh Processing: Cleaning, alignment, and surface reconstruction from scan data.
  • Parametric CAD Rebuild: Native SolidWorks parts and assemblies built for editability, with feature history you can change later.
  • GD&T & Tolerance Strategy: Critical dimensions identified, measured, and documented per ISO/ASME.
  • Manufacturing-Ready Deliverables: STEP/IGES/STL exports plus 2D drawings for supplier quoting and production.

How We Work

A four-step process that turns a physical object into a design you own.

1. Part Assessment

We define which features are critical — fits, mating surfaces, moving interfaces — and agree an accuracy target before anything is captured.

2. Capture & Process

The part is scanned and measured. Scan data is cleaned, aligned, and converted into a workable surface model.

3. Parametric Rebuild

Geometry is rebuilt feature-by-feature in SolidWorks so the model can be edited, toleranced, and revised — not just looked at.

4. Validation & Handoff

Critical dimensions are checked against the physical part, then we deliver native CAD, neutral formats, and drawings.

When Reverse Engineering Makes Sense

Scan-to-CAD pays off whenever a physical part is the source of truth and the digital file is missing.

Legacy Parts & Obsolescence

Keep equipment running when original drawings and suppliers no longer exist. One physical sample is enough to start.

Spare & Replacement Parts

Reproduce a single component or a small batch without re-engineering the whole assembly from scratch.

Design Improvement

Start from a proven physical design and fix its weak points — strength, cost, tolerances, or manufacturability — with FEA and DFM support.

Need the rebuilt model taken further? See our mechanical design and DFM review services, or prototype the result with prototyping support.

What You Receive

Every reverse engineering project ends with files your team and your suppliers can actually work from.

Native SolidWorks Files

Editable parts and assemblies with rebuildable feature history — not imported "dumb" bodies.

Neutral Formats

STEP, IGES, and STL/3MF exports for any CAD system, simulator, or manufacturing partner.

Drawings & Validation Report

2D manufacturing drawings with dimensions and GD&T, plus a report of measured deviations and reconstruction assumptions.

Reverse Engineering FAQ

How accurate can the CAD model be?

Accuracy depends on part size, geometry, and the digitizing method. We agree a target before capture and validate it on critical features — accuracy targets follow your drawing tolerances on critical dimensions.

Can you work from a worn or damaged part?

Yes. Missing geometry is reconstructed from symmetry, mating parts, and function, and every assumption is documented in the delivery report.

What files do I get?

Native SolidWorks parts and assemblies, STEP/IGES neutral files, STL/3MF print files, and 2D drawings in PDF and DWG as needed.

Turn a Physical Part Into a Design You Own

Send photos, drawings, or the part itself — we will scope the digitizing plan and quote the rebuild before any work starts.
