CAD Modeling of Part Assemblies Using Reverse Engineering Technique

Abstract

This paper aims to highlight the utility of implementing the Reverse Engineering Technique in designing assembly parts in the field of industry. Starting from the iconic part models the project begins with the specific stages for Reverse Engineering technique, the part digitization by means of a 3D scanning system, followed by the reconstruction of the solid type parts, and ending with their parameterization. Parameterization is of great importance especially in what concerns the automated obtaining of the part models, since this allows updating the solids along with the change of parameters. In this paper it will be also presented a case study - done by means of the CATIA software package – which demonstrates the creation of parametric solids starting from physical parts for which no technical documentation is available.
