It's not that useful, except for artworks. The copy has less precision than the scan, which has less precision than the original object, which has less precision than its design. If you scan an auto part, you're unlikely to get a usable duplicate auto part.
I feel like AI could help with this by intelligently asking questions and refining the design. "Is this a flat surface? What is the radius of this curve? What is the exact distance between these two edges?"
