What you get from reverse engineering
- Parametric CAD (STEP, IGES; native SolidWorks, Fusion 360 or Rhino on request): a feature-based model with dimensions, fillets and holes you can edit — not a traced mesh.
- Manufacturing drawings: 2D drawings with GD&T on request.
- Scan-to-CAD deviation report: color map and tolerance table showing where the CAD deviates from the scanned part.
- Print-ready mesh (STL/OBJ): when a replica is all you need.
When reverse engineering is the right tool
- Discontinued or legacy parts with no drawings — classic cars, aircraft interiors, industrial machinery, film props
- Worn or broken parts that must be reproduced to original dimensions
- Supplier or competitor parts you need to fit to, mate with or replace
- Hand-sculpted masters (jewelry, product design, sculpture) that need to become manufacturable CAD
- As-built documentation of tooling, fixtures and molds
How the process works
- Scan — structured-light or laser capture at our Glendale studio; large parts are scanned on-site anywhere in Los Angeles County.
- Model — an engineer rebuilds the part as a solid model over the scan reference, restoring nominal dimensions (a worn 10.02 mm bore becomes a 10.00 mm design bore) and capturing design intent.
- Verify and deliver — the CAD is compared back to the scan; you receive the model, a deviation report and the raw mesh.
Reverse engineering pricing in Los Angeles
Scan-to-CAD projects typically start around $500 for simple brackets and housings and run to several thousand dollars for complex assemblies or freeform surfaces. The biggest cost driver is surface type: prismatic parts (flat faces, holes, fillets) model quickly; organic or Class-A surfaces take longer. Send photos and dimensions for a same-day estimate, and see how much 3D scanning costs for the scanning portion.

Reverse engineering FAQs
What file formats do you deliver?
STEP and IGES for any CAD system; native SolidWorks, Fusion 360 or Rhino files on request; STL and OBJ meshes for 3D printing.
How accurate is the CAD model?
Accuracy depends on the scanner and part size; every deliverable includes a deviation report that states the achieved accuracy against the scan. The CAD itself is modeled to nominal design dimensions.
Can you reverse engineer a part that is broken or worn?
Yes. We scan what exists, restore symmetry and nominal dimensions, and model missing geometry from the intact side or reference photos.
Do I need to ship the part?
Small parts can be mailed or dropped at our Glendale studio; anything large is scanned on-site in the Los Angeles area.
How long does it take?
Simple parts typically take 2–4 business days; complex assemblies 1–2 weeks. Rush service is available.
Do you sign NDAs?
Yes, before you send anything.
