When this is the right service
- The OEM is gone, the part is obsolete, or the supplier will not share the drawing.
- The part is worn, broken or deformed and you need the original shape back.
- A casting, forging or moulded part exists but its pattern or tool data is lost.
- You need a drawing for a machine that has run for years without one.
- You want a made part compared with the original to see what changed.
How we rebuild a spare part with no drawing
- Brief and part review. You send a photo, the approximate size, the material if you know it and the job the part does (what it fits into, what loads it takes). If you have the mating part, send it too: it tells us what really matters on the part.
- 3D scan. We scan the part at our Coimbatore facility, or where it stands at your plant. Handheld blue-laser scanning suits small to medium parts, castings and tooling; optical-tracking scanning suits large parts. Shiny or dark surfaces and deep holes can change the method, so tell us the surface.
- Mesh cleaning. The scan is merged, cleaned and checked for gaps, so the mesh matches the part. The mesh can be delivered as STL or PLY.
- CAD rebuild and tolerance. We rebuild the part as a clean, editable CAD model from sections and features of the scan, not as a copy of the rough mesh. On a worn part we rebuild the intended shape, not the wear. Fits, tolerances and mating features are agreed with you, because the scan shows the part as it is today and not what the designer intended. We do not promise a tolerance until we have seen the part and its job.
- Inspection against the scan. We compare the finished CAD with the scan and show the difference as a deviation colour map, so you see where the model sits on the scan before anything is made. Inspection reports are normally delivered in 2 to 3 days.
- Delivery. You receive STEP (also IGES or Parasolid on request) that opens in your own CAD software, plus the mesh and the deviation report if you want them. A 2D drawing can be made from the CAD on request.
What we need from you: a photo, the size, the material and the function of the part, the mating part if you have it, and the tolerance or fit if you know it.
What you receive
| Deliverable | Use |
|---|---|
| Editable CAD (STEP, IGES, Parasolid) | Machining, casting, 3D printing, redesign; opens in your own CAD software |
| STL or PLY mesh | Reference, 3D printing, visual checks |
| Deviation colour map and report (PDF) | Shows the CAD matches the scan; dimensions and GD&T callouts on request |
| 2D drawing (on request) | Shop-floor and supplier use |
What decides the cost
We quote per job and do not publish a price list. The main drivers are:
- the size and number of parts,
- how complex the shape and surfaces are,
- the fit and tolerance you need,
- the output (a mesh is quicker than a full CAD model),
- on-site work, travel and accommodation.

Why scan first
A scanner captures the whole surface of the part, including curves and freeform shapes that are hard to measure by hand. The JINUOSH Vertex handheld blue-laser scanners we distribute are specified by the maker at up to 0.020 mm (Vertex3D and Vertex3D Pro) and 0.025 mm (Vertex Tracker). That is a scanner specification, not a guarantee for every part; we tell you the expected accuracy for your part before we start. See the JINUOSH Vertex scanners. For the numbers by model, read handheld 3D scanner accuracy.
Part of a wider service
To check a made part against CAD or a drawing, see our CMM inspection services in Coimbatore. For machine spares by part type, see industrial machinery 3D scanning and spare parts in India; for cast parts and patterns, see casting and foundry 3D scanning and inspection in India. This is one use of our 3D scanning services in India and reverse engineering services in India. In Coimbatore? See 3D scanning services in Coimbatore. Choosing between providers? Read how to choose a 3D scanning service. Weighing scanners? See JINUOSH Vertex vs Creaform, Shining 3D and GOM. Need a printed copy or fit-check of a scanned part? See 3D printing from your 3D scan. For how a scan becomes an editable model, read scan to CAD in SolidWorks.
