If a sheet metal component is scanned repeatedly by turning it on turn table, what effect it has on quality of scan
The minimal volume you can scan using Revpoint scanner Is 10x10x10 mm , a metal sheet is more than that so don’t expect to get full scan .
For reference yes but you will need to add additional volume for tracking support or a lot of markers, still the scan will be only usable as reference.
Without it you get nothing but Mandala .
