This book contains a research in reverse engineering by manufacturing an industrial mechanical product that had no design schemes throughout the 3D-Scanners. Getting a geometric CAD model from 3D scanner to present physical model. This is generally used in specific applications, like commercial plan and manufacturing tasks.Having a digital data as stereolithography (STL) file. Then it could be easy to manufacture parts unknown documentation and transferred the G-Code to CNC-machines. In this work, modification was proposed and used in RE program which is from Geomagic software's that famous...
