In this thesisi, the reconstruction of the model of the guide vane through the reverse engineering process is conducted. The given vanes, two different modes, were first scanned in separate scanning systems, Shining Einar-Pro and Atos Triple Scan. Subsequently, filling the holes in the Mesh model was done by means of the Athos Professionals software packgae. The next step was to create a CAD model of a scanned vane. For the guide vane, scanned by Shining EinscanPro system, we had a blueprint and we pulled the CAD model out of it while for the model scanned by the Atos Triple Scan System we did not. Hence, we had to extract the dimensions from the scanned model using specific commands of the Atos Professional Software. Once the dimensions were obtained, a model is drawn as it was needed for the transition to the next step. The comparison between the dimensions of the Mesh and the CAD model also occurred in the above software. The comparison is illustrated by the diagram showing the deviations of the level of uniformity, the cylindricity, and the deviation of the dimensional tolerances.
