Reverse Engineering & Replacement Parts
Recover Engineering Knowledge. Rebuild Confidence in Existing Products.
We transform physical components, legacy products and incomplete engineering information into accurate digital engineering data that supports redesign, manufacturing, maintenance and future product development.
Customer problems
Are missing engineering records preventing your next step?
Missing or unreliable product information can stop maintenance, sourcing, redesign, and manufacturing. Reverse engineering restores the knowledge needed to move forward.
- 01Original CAD models are missing.
- 02Drawings have been lost.
- 03Suppliers no longer exist.
- 04Legacy equipment has no documentation.
- 05Spare parts need to be reproduced.
- 06Existing products require redesign.
- 07Manufacturing information is incomplete.
- 08Product modifications cannot begin.
Why this happens
Engineering knowledge disappears when physical products outlive their original records.
Legacy products and equipment often remain valuable long after their suppliers, drawings, and original engineering systems have changed.
- Documentation has been lost.
- Legacy products pre-date digital CAD.
- Engineering records were never maintained.
- Imported equipment arrived without engineering information.
- Suppliers have changed.
- Existing drawings no longer match production.
- Products evolved without updated documentation.
PART INSPECTION / VERIFICATION
Recover reliable engineering information from the physical product.
Inspection, measurement, reconstruction, and verification turn existing hardware into dependable digital engineering data.
How GilMan Engineering helps
Reverse engineering grounded in physical evidence and engineering verification.
We support physical part inspection, measurement strategy, CAD reconstruction, assembly recreation, engineering verification, manufacturing documentation, product redesign, and supplier-ready deliverables.
01
02
Verified CAD and documentation
CAD reconstruction, assembly recreation, engineering verification, and manufacturing documentation restore usable product knowledge.
03
Redesign and supplier support
Product redesign support and supplier-ready deliverables help teams reproduce, modify, and sustain existing products.
What we deliver
Recovered engineering outputs ready for manufacturing, maintenance, and redevelopment.
The deliverable is shaped around the product and its next use, from a recreated part model to a verified assembly and complete digital engineering archive.

Frequently asked questions
Questions before we start.
Can you recreate missing CAD models?
Yes. We inspect and measure physical components, reconstruct their geometry, and prepare accurate, usable CAD models.
Can you reverse engineer complete assemblies?
Yes. We can recreate individual parts, assembly relationships, interfaces, and product structures for complete assemblies.
Can you reproduce obsolete components?
Yes. We develop verified CAD models, drawings, and supplier-ready data to support the manufacture of obsolete replacement parts.
Can you work from worn or damaged parts?
Yes. We assess wear and damage, compare related features and interfaces, and apply engineering judgement to recover the intended geometry.
Can you create manufacturing drawings?
Yes. We can turn reconstructed engineering data into clear manufacturing drawings and supporting technical documentation.
Can you support redesign projects?
Yes. Recovered product knowledge can be used as the foundation for design updates, product improvements, and manufacturing preparation.
Can you prepare supplier documentation?
Yes. We prepare neutral CAD, drawings, dimensional information, and structured deliverables for supplier review and manufacture.
Can you work with imported equipment that has no engineering data?
Yes. We can inspect imported equipment and recreate the engineering information needed for maintenance, replacement parts, modification, or supplier transition.
