Reverse Engineering: Generation of Cad Model from Scanned Mesh File Captured using 3d Scanner

Reverse Engineering is the method of capturing an existing object’s physical characteristics and reproducing a replica of it
from the extracted data. This technique is widely recognized as a predominant technique in aerospace design & manufacturing. It is hard to reproduce a duplicate of any part or model the part when original designs are not available specifically in the case of legacy aircrafts. In this technique, various stages involved are data acquisition (scanned mesh file) using 3D scanning, feature extraction, segmentation to fit free form shapes and developing a 3D CAD model. This research paper signifies the role of reverse engineering in restoring the legacy features of aircraft components especially for an aging fleet
