Reverse Engineering Services Australia
Scan-to-CAD reverse engineering for obsolete parts, legacy components and end-use documentation. Sub-millimetre accuracy. Australia-wide service from our Brisbane facility.
What Is Reverse Engineering?
Reverse engineering is the process of analysing an existing physical component to extract its design specifications — dimensions, tolerances, materials and geometry — and reconstruct it as a digital CAD model. At 3Dmatic, we use metrology-grade 3D scanning combined with parametric CAD reconstruction to deliver manufacturing-ready files from physical parts, worn components, or legacy equipment where no original drawings exist.
Our Reverse Engineering Process
1. Part assessment
We assess the component — condition, material, complexity, and required tolerances — and advise on the best scanning approach. Parts can be shipped to us or we can visit your site for large fixed equipment.
2. 3D scanning
We capture the part geometry using structured-light or laser scanning, producing a dense point cloud accurate to ±0.05 mm. Multiple scan positions are merged to capture complete geometry including internal features where accessible.
3. CAD reconstruction
The point cloud is converted into a clean parametric CAD model in SolidWorks or Fusion 360. We correct wear and damage during this phase, delivering a model that represents the part as-designed rather than as-worn.
4. Manufacture
The verified CAD file is ready for any manufacturing process — 3D printing, CNC machining, casting or stamping. We can produce the replacement part directly or supply the file to your preferred manufacturer.
Industries We Serve

- Aerospace & defence components
- Medical devices & dental prosthetics
Scanning Technology and Accuracy
The quality of a reverse-engineered model depends entirely on how the part is captured. We match the scanning method to the geometry, size and tolerance of each component rather than relying on one technique for everything.
Structured-light scanning
Our primary method for small to medium parts. Projected light patterns capture dense, high-resolution geometry to ±0.05 mm, ideal for detailed components, freeform surfaces and parts with fine features.
Laser scanning
Used for larger components and on-site capture of fixed equipment that cannot be shipped. Laser scanning handles dark, reflective and difficult surfaces that challenge other methods, and covers large volumes quickly.
From point cloud to parametric model
A raw scan is a mesh, not a usable engineering file. The real work is the reconstruction: we rebuild the part as a clean, fully parametric CAD model with proper features and editable dimensions — not a frozen “dumb” solid. That means you can modify the result later, and it carries accurate tolerances rather than the noise and wear captured in the scan. Where a part is worn or damaged, we restore it to its as-designed condition during reconstruction.
When You Need Reverse Engineering
Reverse engineering solves a specific problem: you have a physical part but no usable design data. The common triggers we see across Australian industry are:
- Obsolete or discontinued parts — the original supplier is gone or the component is no longer made, and you need to remanufacture it.
- No original drawings — legacy equipment where the CAD or technical drawings never existed or have been lost.
- Replacement of a worn component — capture the part, restore it to its original design intent, and produce an accurate replacement.
- Design modification — recreate an editable model so an existing part can be improved, strengthened or adapted.
- Digitising a hand-made or sculpted master — turn a physical pattern or prototype into a manufacturable CAD file.
- Quality inspection — compare a manufactured part against its intended CAD to verify it was made to spec.
Frequently Asked Questions
What is the accuracy of your reverse engineering scans?
Our structured-light scanners capture geometry to ±0.05 mm. The final parametric CAD model is built to match this accuracy, with tolerances clearly documented in the delivery package.
Can you reverse engineer parts that are heavily worn or damaged?
Yes. We scan the worn part to capture its current geometry, then use engineering judgement to reconstruct the original design intent — correcting wear patterns, restoring symmetry, and rebuilding damaged features digitally before producing the replacement.
What file formats do you deliver?
We deliver native SolidWorks (.sldprt), STEP, IGES and STL files as standard. Additional formats available on request. We also supply 2D manufacturing drawings in PDF and DWG format if required.
Can you visit our site for large equipment?
Yes. For components that cannot be removed from machinery — large pump housings, fixed industrial equipment, vehicle frames — we can travel to your site across Australia. Contact us to arrange a site visit quote.
