3D scan and Reverse Engineering of a pine shaped object

3D scan and Reverse Engineering of a door handle

TetraVision digitized this beautiful door handle.

Process

Setup in free state with some reference points on the object
Spraying of the object with water based anti-reflex spray
Digitizing of the object
Due to the water based scanning spray, the object can be cleaned easily afterwards

Used technology

GOM Atos III triple scanner with a 100mm measurement volume
Automated rotation table

Post processing

Closing some small holes.
Filtering of the scan to reduce the file size.

We also converted this scan to a CAD file.

3D scan results

Reverse Engineering

For this project we needed to convert the *.stl data to *.stp (step-file) or CAD data so that our client could incorporate the file right away in their CAD software.

We converted the artistic / sculpted portion of the object with an autosurfacing functionallity and the more geometric portion by using traditional sketching.

With the autosurfacing there is a slight loss of detail, but the final model still captures the original intend of the artist.
We also splitted the model in different bodies so that parts of it could be re-used in future designs.
