- Worth noticing
- The page shows a 238 MB scan reduced to 20 MB, with the surface reportedly moved by thousandths of a millimetre.
Field notes
The first program's listed operations include levelling against a picked face or detected flat area, aligning an edge to an axis, and placing the origin at a chosen point such as a hole centre. The comparison workflow accepts either automatic best fit or three matched point pairs, then presents deviations through colours, callouts, a histogram, and summary statistics. The page also links to a sample report and says the original scan remains untouched during edits.
