CAD Model Created from Polygon Mesh

Abstract:

The paper deals with a description of the creation of CAD model (file format .IGES) based on polygon mesh (file format .STL) obtained by 3D scanning. On the basis of the imported polygon mesh into Reverse Engineering software, it is possible to create surface (or solid) CAD model. For CAD model created from a polygon mesh, a model of screw propeller was chosen. The paper also presents a color deviation map acquired by comparison between a polygon mesh and a CAD model. The 3D digitizing was performed by 3D scanner GOM ATOS II SO TripleScan; GOM ATOS Professional v7.5 SR2 software was used for processing of the scanned data and Delcam PowerSHAPE 2015 CAD software was used for reverse modeling.
