Scanning in combination with Reverse Engineering
To reproduce this part, we made an optical 3D scan and used it as a reference for reverse engineering a new CAD model.
We used an ‘auto-surface’ modelling approach.



Process: step by step
Process
- NO spray needed
- Scanning in “free state,” with some reference points on the rod.
- Digitizing the whole thing + converting to CAD
Technology
- GOM Atos III Triple scan with 320MV (measuring volume)
- Automatic rotation table
- Geomagic Design X
Post-processing
- Plugging holes + Auto-surfacing
- Scan filtering to reduce file size.
3D Scan results
The screenshots below show the final mesh and reverse engineering CAD model.
