The paper describes about the state of art technology in preparing the existing component using digitized data by using optical scanners. Whereas the copy milling and CMM process was a traditional process by which the data could not be generated for creating a CAD model with precise accuracy. The study also in visages how to generate the Cloud point data and how it can be converted into CAD model for the given product using Polyworks software. The CAD file formats (i.e. ply & STL) i.e. cloud point data conversion which is generated by using white light scanner was further investigated with the other reverse engineering software’s such as Image ware and Polyworks. The digitization process for the given component was developed using the Breuckmann OPTOCAT White light scanner. The modeling irregularities in the component were observed and studied using the reverse engineering software. The methodology adopted in this research is such as scanning, data preparation and Quality Checks of the material were studied [1].
