Tutorial: Deviation Analysis in Quicksurface (Mesh compared to CAD)

For a project I need to create large carbon molds. Initially I started with PLA+ but the basically melted while baking the carbon (who would have guessed...). The next iteration uses PETG but I was a bit skeptical about their accuracy after printing since it shrinks and warps much more than PLA+ (did a test a while back and yeah, it really does). Since I have the Einscan Rigil I scanned them right after printing (and letting them cool) without needing to bring a PC to my workshop. After processing the scans directly on the Rigil I used Quicksurface Pro for the deviation analysis. To perform a proper analysis the meshes need to be aligned to the CAD models and here lie some pitfalls: The side of the mold shrank and therefore impede the alignment so the relevant parts for alignment need to be isolated. I also showed the scan process in a shorter video.
