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.

  • Original CAD models are missing.
  • Drawings have been lost.
  • Suppliers no longer exist.
  • Legacy equipment has no documentation.
  • Spare parts need to be reproduced.
  • Existing products require redesign.
  • Manufacturing information is incomplete.
  • Product 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.

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.

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?
