Legacy and obsolete parts
Recreate components whose drawings, models or suppliers no longer exist.
Reverse engineering & 3D scanning
The drawings are gone. The part still has to exist.
Dynamics Group captures legacy parts with Artec Leo 3D scanning and conventional metrology, reconstructs usable CAD, and can machine the replacement in the same building.

Where we fit
From physical part to manufacturable data
A point cloud is not a drawing. The engineering value is deciding design intent — which surfaces are critical, which dimensions were nominal, what the original tolerance probably was — and documenting it so the part can be made again, correctly.
Scan-to-CAD reconstruction
Parametric CAD rebuilt from scan data with engineering judgment, not auto-surfacing alone.
Damaged-part recovery
Reconstruct worn or broken geometry back to its intended form before remanufacture.
Fit and interface checks
Compare as-built parts against CAD or mating hardware with full-surface scan data.

How a quote starts
Send enough context to get a useful answer
-
01
Show the requirement
A drawing, model, marked-up photo, layout or statement of work is enough to begin.
-
02
Name the decision
Quantity, timing, critical features and acceptance requirements keep the quote focused.
-
03
Review together
We identify risk, missing data and the best process before committing your schedule.
Buyer questions
Straight answers before you send a print
What do I get — a mesh or real CAD?
Deliverables are agreed up front: raw scan mesh, parametric CAD, a drawing with proposed tolerances, or a finished machined part. Most customers want CAD plus the part.
How accurate is the scan data?
Scan accuracy depends on part size, surface and geometry; critical datum features are verified with probe and CMM measurement rather than relying on scan data alone.
Can you reverse engineer a worn part?
Yes. Worn surfaces are reconstructed to intended geometry using the remaining evidence, mating parts and engineering judgment — with assumptions documented for your approval.
Is my part's data protected?
Yes. Scans, reconstructed CAD and drawings are handled under restricted access in an ITAR-registered facility and belong to you.
Can you reverse engineer an obsolete part with no drawings?
Yes. Obsolete and legacy parts are the common case. The surviving part is scanned, the intended geometry is reconstructed from the remaining evidence and mating components, and you receive CAD and a drawing so the part can be reordered without depending on the original supplier.
Where is reverse engineering for obsolete parts performed?
In the United States, at the Madison Heights, Michigan facility outside Detroit. Scanning, CAD reconstruction, machining and inspection all happen in one building, so an obsolete part can go from scan to replacement without leaving the shop.
Have a print, model or tooling problem?
Send what you have. We will tell you where we fit, what is missing and the fastest practical next step.
